Best Spark Plugs For Gmc Sierra: Compare 10 Options
A strong GMC Sierra spark plug choice matches the truck’s exact year and engine, supplies the right number of plugs, and uses a suitable electrode material. For owners of 2014–2020 Sierra 1500 5.3L or 6.2L V8 models, the eight-plug NGK Laser Iridium set listed for those applications is the most directly matched option here. Older Sierra owners can consider the TICANEE 41-962 set, which lists GMC Sierra fitment for 1999–2007 Classic models, or the Ozikutech iridium set, which lists Sierra 1500 applications through 2013.
This roundup also includes plug-and-wire kits and general GM replacement plugs, but their fitment descriptions differ. Confirm the truck’s year, engine, and OE plug number before ordering; a familiar plug designation alone does not establish compatibility.
The best match in this selection for a listed newer Sierra application is Sixity Auto NGK Laser Iridium: its eight plugs are specified for GMC Sierra 1500 5.3L and 6.2L V8 models from 2014 through It leads because the product data names the GMC model, engine sizes, and years directly, rather than relying on broad GM fitment. Owners of other Sierra years should instead match their engine and OE number to options such as TICANEE 41-962 or Ozikutech Iridium before buying.

Detailed Reviews: Best Spark Plugs For Gmc Sierra

#1 · Best Overall
1. Sixity Auto NGK Laser Iridium
- Core Material: Iridium
- Top Material Type: Ceramic
- Compatible with Vehicle Type: Truck
- Thread Size: 0.04 in
Best for: For 2014–2020 Sierra V8s.
Why it ranks #1: Its eight genuine NGK Laser Iridium plugs explicitly fit GMC Sierra 1500 5.3L and 6.2L V8 models from 2014 through 2020.
Explicit GMC Sierra 1500 fitment for 2014–2020 5.3L and 6.2L V8 engines is the clearest advantage of this eight-piece NGK Laser Iridium set.

The stated Sierra 1500 fitment covers the 2014 through 2020 model years with either a 5.3L or 6.2L V8, so buyers can screen by both engine and year. The eight-plug quantity suits a full set, and the listing says the plugs are genuine NGK parts with original packaging and hardware. It also identifies them as direct replacement auto parts. The supplied fitment details provide a narrower application window than broad GM-engine listings.
- Names GMC Sierra 1500 2014–2020 fitment
- Covers 5.3L and 6.2L V8 engines
- Eight NGK Laser Iridium plugs included
- Listing identifies genuine NGK parts and direct replacement parts
- Listed Sierra fitment ends at the 2020 model year.
Skip it if you own a 2021–2024 Silverado 1500 5.3L or 6.2L; NGK Iridium IX plugs are listed for those Silverado applications.
This set suits owners of a 2014–2020 GMC Sierra 1500 with a 5.3L or 6.2L V8 seeking eight NGK Laser Iridium replacements. Its stated Sierra year range does not extend beyond 2020.

#2 · Best Classic Fit
2. TICANEE 41-962 Platinum
- Core Material: Platinum
- Top Material Type: Platinum
- Compatible with Vehicle Type: Truck, SUV
Best for: For 1999–2007 Classic GM trucks.
Why it ranks #2: The eight-plug platinum set lists GMC Sierra and Yukon fitment for 1999–2007 Classic models and several matching GM OE numbers.
TICANEE explicitly lists GMC Sierra and Yukon fitment for 1999–2007 Classic models, making this eight-pack a targeted option for older GM trucks and SUVs. Its 41-962 plugs are described as direct replacements for several OE numbers, including 41-962 and 41-110, to help identify the intended replacement family.
The stated vehicle list covers Sierra and Yukon through 2007 Classic, alongside several Chevrolet trucks and SUVs, which helps owners of older GM platforms narrow the application. TICANEE describes the plugs as plug-and-play direct replacements and names multiple OE references, including 41-962, 41-110, and 19299585. Eight plugs are included, matching a full-set quantity for a V8. The listing also identifies platinum core and top materials, but its specified range does not extend to later Sierra models.
- Names GMC Sierra 1999–2007 Classic fitment
- Eight plugs included for a full-set quantity
- Platinum core and top materials
- Lists multiple OE replacement references
- Stated GMC Sierra range ends with 2007 Classic models.
Skip it if you have a 2014–2020 Sierra 1500 5.3L or 6.2L; Sixity Auto's NGK Laser Iridium set lists those later applications.
This set fits buyers with a listed 1999–2007 Classic GMC Sierra application seeking eight platinum plugs and OE-reference guidance. Its specified Sierra coverage does not include later model years.

#3 · Broad Sierra Coverage
3. Ozikutech Iridium 41-110
- Core Material: Iridium
- Top Material Type: Iridium
- Compatible with Vehicle Type: for 4.8 5.3 5.7 6.0 6.2 6.6 8.1 LS V8
Best for: For older GM V8 applications.
Why it ranks #3: This eight-pack lists GMC Sierra 1500 4.8L, 5.3L, 6.0L, and 6.2L applications through 2013 and a 0.04-inch gap.
This Ozikutech eight-pack lists a 0.04-inch gap and iridium construction, alongside replacement references including 41-110, 41-162, and 41-985. Its stated vehicle coverage includes GMC Sierra 1500 4.8L, 5.3L, 6.0L, and 6.2L engines from 2000–2013, targeting a substantial range of older V8 applications.
The listed 0.04-inch gap gives buyers a concrete specification to compare with their application, while the iridium material and eight-piece quantity position the set for a full V8 replacement. Ozikutech names several OEM replacement numbers, including 41-110 and 41-162, and identifies Sierra 1500 2000–2013 with 4.8L, 5.3L, 6.0L, and 6.2L engines. Its broad GM fitment list helps cross-reference vehicles, but the stated Sierra years stop before newer generations.
- Eight iridium spark plugs included
- 0.04-inch listed gap
- Names Sierra 1500 2000–2013 engine coverage
- Lists multiple OEM replacement references
- Stated Sierra 1500 fitment does not cover model years after 2013.
Skip it if you own a 2014–2020 Sierra 1500 5.3L or 6.2L; Sixity Auto's NGK Laser Iridium set lists that generation's fitment.
Consider this set for a listed 2000–2013 Sierra 1500 V8 application when the 0.04-inch gap and replacement references match your requirements. It does not list newer Sierra years.

#4 · Plugs and Wires
4. TICANEE 41-110 Plug and Wire Set
- Core Material: Copper
- Top Material Type: Iridium
- Compatible with Vehicle Type: Chevrolet, GMC, Cadillac
- Thread Size: M14x1.25
Best for: For combined plug-and-wire service.
Why it ranks #4: The plug-and-wire kit names GMC Sierra in its compatibility and provides eight spark plugs plus wires, with OE reference 41-110.
TICANEE pairs spark plugs with ignition wires in this replacement set, addressing two service components together for listed GM vehicles. The listing names GMC Yukon and Sierra among its applications and identifies OE references 41-110 and 12621258, while describing the plugs as direct replacements intended for plug-and-play installation.
The combined plugs-and-wires format can simplify parts selection for a service involving both components, and the listing calls the replacements plug-and-play. It names GMC Sierra and Yukon applications and provides additional verified coverage for several Express V8 configurations, including 5.3L, 4.8L, and 6.0L variants. The plug materials are specified as copper core and iridium top, with M14x1.25 threads. The supplied Sierra details do not give a complete year-by-year range, so precise application remains important.
- Includes spark plugs and ignition wires
- Names GMC Sierra and Yukon among applications
- Lists OE references 41-110 and 12621258
- M14x1.25 thread specification
- Supplied details do not give a complete GMC Sierra year-by-year range.
Skip it if you need a clear Sierra 1500 year and engine range; Sixity Auto's NGK Laser Iridium set lists 2014–2020 5.3L and 6.2L V8 fitment.
This TICANEE set suits buyers seeking plugs and wires together for a listed GM application. It names Sierra but lacks a complete year-by-year Sierra range, so match the OE references to the vehicle.

5. JDMSPEED Iridium Plug and Wire Kit
- Core Material: Iridium
- Top Material Type: Iridium
- Compatible with Vehicle Type: Truck, SUV
- Thread Size: M14x1.25
Best for: For plugs-and-wires replacement.
Why it ranks #5: This kit includes eight 3186 plugs and eight wires, and its title names GMC Sierra alongside several GM V8 models.
This JDMSPEED package combines eight iridium spark plugs with eight M8-48322 spark plug wires, putting ignition components together in one kit. Its title names GMC Sierra among the intended vehicles and lists 5.3L, 6.0L, and 6.2L engines, offering a combined-parts option rather than plugs alone.
Including eight plugs and eight wires makes this package relevant to buyers replacing both ignition components in one service, rather than sourcing wires separately. The listing provides an extensive set of replacement part numbers and names GMC Sierra, Yukon, and several Chevrolet applications. It also specifies a 14mm x 1.25 thread for the plugs. The supplied information does not provide a Sierra year-by-year fitment breakdown, so the model and engine names alone do not establish every specific application.
- Eight iridium spark plugs included
- Eight M8-48322 spark plug wires included
- Title names GMC Sierra and 5.3L, 6.0L, and 6.2L engines
- 14mm x 1.25 listed plug thread
- No year-by-year GMC Sierra fitment range is provided.
Skip it if you want an explicit Sierra model-year range; Sixity Auto's NGK Laser Iridium set lists Sierra 1500 2014–2020 5.3L and 6.2L V8 fitment.
Choose this kit if you want plugs and wires together and your Sierra matches the listed engine and replacement references. The supplied details do not spell out model-year coverage, so application specificity is limited.

6. ACDelco 41-962 Platinum
- Core Material: Platinum
- Top Material Type: Nickel
- Compatible with Vehicle Type: Car
- Thread Size: 14 millimeters
Best for: For platinum electrode durability.
Why it ranks #6: The eight-pack uses double platinum electrode pads and a copper core, but the supplied data does not identify specific Sierra years or engines.
Double platinum pads on both the center and ground electrodes are the defining feature of these ACDelco plugs, helping maintain consistent voltage demands while reducing wear on the ignition system. The eight-plug set also uses a copper core to help keep electrode temperatures cooler during operation.
The double platinum electrode pads focus on durability and consistent voltage demands, which can help limit wear across the ignition system. A pure copper core helps keep the electrode cooler, while the one-piece fired-in suppressor seal blends three glass types to create a gas-tight barrier. That seal is specified to help reduce radio-frequency and engine interference and protect against compression pressures. The listing includes eight plugs, but its vehicle-type specification says car rather than naming a Sierra application.
- Double platinum pads on center and ground electrodes
- Copper core helps maintain cooler electrode temperature
- Suppressor seal helps reduce radio-frequency and engine interference
- Eight ACDelco 41-962 plugs included
- Vehicle compatibility is listed as car, without a named GMC Sierra application.
Skip it if you need a listing that specifically names Sierra engines; NGK Laser Iridium plugs are listed for 2014–2020 Sierra 1500 5.3L and 6.2L V8s.
Choose these if you want ACDelco double-platinum electrodes, a copper core, and an eight-plug set. The listing does not identify GMC Sierra fitment, so this option suits buyers whose application is otherwise verified.

7. NGK TR5GP G-Power Platinum
- Core Material: Platinum
- Top Material Type: Platinum
- Compatible with Vehicle Type: Car, Truck
- Thread Size: 14×1.25mm
Best for: For wider-heat-range operation.
Why it ranks #7: This genuine NGK eight-pack offers platinum construction and a stated wide heat range, though its listing does not specify GMC Sierra fitment.
NGK specifies a wider operating heat range than ordinary plugs for this eight-piece G-Power Platinum set, a feature intended to resist carbon buildup and pre-ignition. Its patented triple-gasket sealing process targets combustion-gas leakage, making this a platinum option for truck owners prioritizing those listed design features.
The wider operating heat range is intended to resist carbon buildup and pre-ignition, useful considerations when selecting plugs for varied engine operation. NGK also specifies a patented triple-gasket sealing process that eliminates the possibility of combustion-gas leakage. The listing identifies the TR5GP model, a 14×1.25mm thread, and compatibility with cars and trucks, but it does not name GMC Sierra engines. Eight plugs are included, so the set quantity is clear while exact vehicle application remains a separate fitment decision.
- G-Power platinum construction
- Designed for a wider heat range than ordinary plugs
- Resists carbon buildup and pre-ignition
- Triple-gasket process addresses combustion-gas leakage
- The listing does not specify GMC Sierra engine or year fitment.
Skip it if you want explicit Sierra 1500 5.3L or 6.2L fitment; Sixity Auto's NGK Laser Iridium set names those engines for 2014–2020.
Consider this NGK set if its wider heat-range design, platinum construction, and triple-gasket sealing suit your priorities. It is listed for cars and trucks, but Sierra-specific engine and year compatibility is not provided.

8. A-Premium Iridium Platinum
- Core Material: Platinum
- Top Material Type: Iridium
- Compatible with Vehicle Type: Truck
- Thread Size: 14
Best for: For broad Silverado V8 coverage.
Why it ranks #8: The eight-plug set lists Silverado 1500 5.3L and 6.2L applications, but the supplied fitment details do not confirm a GMC Sierra.
A-Premium lists Silverado 1500 5.3L and 6.2L V8 coverage from 2014–2023, making its eight-pack notable for buyers seeking a broad stated application range. The plugs combine a platinum core with an iridium top, and the listing identifies a fine-wire design and 0.04-inch gap.
The eight-plug quantity supports a complete V8 set, while the stated Silverado 1500 coverage spans 2014–2023 for both 5.3L and 6.2L engines. A-Premium lists platinum as the core material and iridium as the top material, with a fine-wire description and 0.04-inch gap. The supplied fitment also names several other GM V8 vehicles, but it does not identify GMC Sierra in the excerpt, so Silverado-specific coverage should not be treated as an explicit Sierra application.
- Eight plugs included
- Lists Silverado 1500 5.3L and 6.2L V8 fitment
- Platinum core with iridium top material
- Fine-wire description and 0.04-inch gap
- Supplied fitment excerpt does not explicitly name GMC Sierra.
Skip it if you require Sierra named in the application; Sixity Auto's NGK Laser Iridium set explicitly lists Sierra 1500 2014–2020 5.3L and 6.2L V8s.
This A-Premium set suits Silverado 1500 owners within the listed 2014–2023 V8 range who want eight fine-wire plugs. Its supplied fitment excerpt does not establish GMC Sierra compatibility.

View on AmazonWhy it ranks #9: ACDelco describes this as a GM original-equipment iridium replacement, but it is a two-pack and no Sierra application is specified.
ACDelco identifies its 41-162 iridium plug as an exact replacement for vehicles’ original components, making OE-style replacement the central appeal. Its iridium composition is specified for wear resistance and durability, while the listing also connects the material with stable idling, reliable cold starts, and smooth performance.
The iridium composition is described as having a high melting point and strength, supporting wear resistance and durability. ACDelco also associates the plug with engine idle stability, reliable cold starting, quick acceleration, and smooth performance. Its three-piece fired-in suppressor seal meters spark energy, adding an ignition-control feature alongside the electrode material. This is a pack of two, not a full eight-plug set, so Sierra owners planning a complete V8 replacement need to account for the supplied quantity.
- Iridium composition offers wear resistance and durability
- Listed as an exact replacement for original components
- Supports idle stability and reliable cold starting
- Three-piece suppressor seal meters spark energy
- Pack contains two plugs, not enough for a complete eight-cylinder replacement.
Skip it if you need all eight plugs in one set; A-Premium APSP140 supplies an eight-pack and lists Silverado 1500 V8 fitment.
Choose this two-plug ACDelco option for targeted original-component replacement where its application is confirmed. Its quantity is a poor match for a complete Sierra V8 service unless you obtain the remaining plugs separately.

10. NGK Iridium IX 4344
- Core Material: Iridium
- Top Material Type: Iridium
- Compatible with Vehicle Type: Chevrolet Silverado 1500 5.3L V8, Chevrolet…
- Thread Size: 14mm
Best for: For Silverado Iridium IX buyers.
Why it ranks #10: The eight NGK Iridium IX plugs are specified for Chevrolet Silverado 1500 engines, not GMC Sierra, so the listed use case is a mismatch.
Corrosion-resistant center and ground electrodes are the key feature of these NGK Iridium IX plugs, helping minimize spark-gap growth and preserve ignitability. This eight-pack is specifically listed for 2014–2024 Chevrolet Silverado 1500 5.3L and 6.2L V8 applications, giving Silverado owners a broad stated year range.
NGK says the advanced center and ground electrodes produce efficient combustion and a strong spark, while corrosion resistance helps minimize spark-gap growth over the plug’s life. Those details support buyers focused on sustained ignition performance rather than a basic material-only specification. The listing provides 14mm threads and a 1.1mm gap, and names Chevrolet Silverado 1500 5.3L and 6.2L V8 fitment from 2014 through 2024. Its explicit vehicle applications are Silverado, not GMC Sierra.
- Iridium IX center and ground electrodes
- Corrosion-resistant electrodes minimize spark-gap growth
- 14mm thread and 1.1mm listed gap
- Eight plugs listed for 2014–2024 Silverado 1500 V8s
- The stated vehicle applications name Silverado, not GMC Sierra.
Skip it if you require a listing naming GMC Sierra 1500 fitment; Sixity Auto's NGK Laser Iridium set specifies Sierra 2014–2020 5.3L and 6.2L V8s.
This NGK set fits the stated Silverado 1500 5.3L and 6.2L V8 range from 2014–2024 and favors corrosion-resistant electrodes. GMC Sierra applications are not named in the supplied fitment information.

View on AmazonAvoiding a Sierra fitment mismatch
The main fitment trap is treating a shared GM engine size or plug number as proof that a set fits every Sierra. These listings cover distinct application ranges: Sixity Auto NGK Laser Iridium names Sierra 1500 5.3L and 6.2L V8 models from 2014–2020, while TICANEE 41-962 specifies Sierra and Yukon Classic models from 1999–Ozikutech Iridium 41-110 lists Sierra 1500 engines from 4.8L through 6.2L through 2013.
Those ranges should not be blended into a universal fit claim. Some products instead name Chevrolet Silverado applications, or provide general GM replacement references, without confirming Sierra fitment in the supplied details.
Before ordering, compare the truck’s model year and engine with the full vehicle-fitment listing and verify the OE part number. Check whether the package provides eight plugs; a two-pack such as ACDelco 41-162 is not a complete V8 set.
When a plug-and-wire kit makes sense
A plug-and-wire kit is useful only when the Sierra’s application matches both components and you intend to replace the wires as well. TICANEE 41-110 Plug and Wire Set and JDMSPEED Iridium Plug and Wire Kit each list eight plugs plus wires, which can consolidate parts for a service that calls for both. That inclusion is not automatically an advantage: if the wires are not needed, the additional components do not resolve fitment uncertainty.
The TICANEE listing identifies OE reference 41-110 and names GMC Sierra; JDMSPEED lists several replacement numbers and names Sierra in its title, but buyers should still confirm the exact year and engine against the detailed compatibility information. A plug-only set such as Sixity Auto NGK Laser Iridium is the clearer choice when only plugs are required and its specified 2014–2020 Sierra 1500 5.3L or 6.2L V8 range matches.
How to Choose Sierra Spark Plugs
Year and engine fitment
Start by matching the plug listing to the Sierra’s exact year and engine. The products span different stated ranges: Sixity Auto NGK Laser Iridium specifies 2014–2020 Sierra 1500 5.3L and 6.2L V8 models; TICANEE 41-962 names Sierra and Yukon Classic models from 1999–2007; and Ozikutech Iridium 41-110 lists Sierra 1500 4.8L through 6.2L engines through These are not interchangeable ranges.
For a newer 5.3L or 6.2L 1500, the Sixity listing is the most specific match. For a Classic truck, favor the TICANEE listing if its year and engine agree.
For any other application, verify the OE part number and full fitment before selecting a broader listing.
Electrode material and construction
Choose a listed electrode material only after fitment is confirmed; material labels do not prove a plug suits your engine. Options include platinum in ACDelco 41-962 and NGK TR5GP, iridium in Sixity Auto NGK Laser Iridium and ACDelco 41-162, and an iridium-platinum description in A-Premium Iridium Platinum. ACDelco 41-962 specifically describes double platinum pads and a copper core, while the ACDelco 41-162 listing describes iridium wear resistance and cold-start performance.
If you want a plug set directly tied to a Sierra range, choose based on the matching vehicle details first. If the correct OE replacement is established, compare the material and construction information for that application rather than assuming one material is universally better.
Pack size and included wires
Check whether the package supplies enough plugs for the service and whether it adds wires you need. Most of the listed sets provide eight plugs, including Sixity Auto NGK Laser Iridium and TICANEE 41-962; ACDelco 41-162 is explicitly a pack of two and is not a complete eight-plug set by itself. TICANEE 41-110 Plug and Wire Set and JDMSPEED Iridium Plug and Wire Kit each list eight plugs and eight wires.
A complete eight-plug set suits buyers replacing all plugs on the V8 application specified by the listing. A two-pack may suit a smaller replacement need, but only when the vehicle requires that quantity.
Select a wire kit when the application matches and wire replacement is part of the job.
Which Spark Plugs Should I Choose for My Sierra?
Choose Sixity Auto NGK Laser Iridium if your truck is a 2014–2020 GMC Sierra 1500 with a 5.3L or 6.2L V8; it is the clearest exact fit listed. For a 1999–2007 Classic Sierra, consider TICANEE 41-962 Platinum, whose fitment names that range. If you have a Sierra 1500 from the earlier years covered by its listing, Ozikutech Iridium 41-110 specifies 4.8L, 5.3L, 6.0L, and 6.2L applications through 2013.
Choose TICANEE 41-110 Plug and Wire Set or JDMSPEED Iridium Plug and Wire Kit only when you also need wires and confirm their detailed fitment. For any other year or engine, verify the OE number before ordering; Silverado-only fitment is not confirmation of Sierra compatibility.

Frequently Asked Questions
How do I verify spark plug fitment for my GMC Sierra’s year and engine?
Check your Sierra’s year and engine, then compare them with the product’s listed applications and OE number. Prefer listings that name the GMC Sierra and the exact engine and years. If the listing only names a Silverado or gives broad GM fitment, do not assume it confirms Sierra compatibility; verify the OE number before ordering.
When should I replace spark plugs and wires on a GMC Sierra?
Follow the maintenance schedule for your specific Sierra and engine, and check the vehicle’s service information for the recommended interval. Plug-and-wire replacement timing can vary by application and part. If you are considering a kit, confirm that both the plugs and wires match your truck rather than assuming the listing covers every Sierra.
Should I replace all eight spark plugs at once?
For a V8 Sierra, replacing the complete set of eight is a practical choice when the plugs are due, provided the set is confirmed for your engine. A complete set keeps the replacement consistent across the engine. If only one plug is being addressed, first identify the cause and follow the service guidance for your application.
Does Silverado fitment confirm compatibility with my Sierra?
No. A Silverado-only application does not confirm that a plug fits a GMC Sierra, even when the listing names similar engines. Look for Sierra-specific year and engine coverage or verify the plug’s OE number against your truck.
If that information is missing, confirm fitment before ordering rather than relying on a broad GM description.
Should I choose a spark plug kit that includes wires?
Choose a plug-and-wire kit only if you need wires as well as plugs and its detailed fitment matches your Sierra’s year and engine. The inclusion of wires does not establish compatibility by itself. If you need plugs only, compare plug-only options and verify their listed application and OE number before buying.
Final Words
For a 2014–2020 Sierra 1500 with a 5.3L or 6.2L V8, Sixity Auto NGK Laser Iridium is the clearest match in this selection because its listing names those applications directly. For a 1999–2007 Classic, consider TICANEE 41-962; for earlier applications covered by its listing, check Ozikutech 41-For other trucks, verify engine and OE number, and confirm wire-kit fitment separately.
