Best Spark Plugs For Nissan Frontier by Engine and Plug Type

#1 · Best Overall

1. Sixity Auto NGK Iridium IX

• Core Material: Iridium
• Top Material Type: Metal
• Compatible with Vehicle Type: Car, Truck
• Gap Size: 1.1 millimeters

Best for: NGK Iridium for 4.0L V6.

Why it ranks #1: The six-plug set specifies 4.0L V6 Frontier fitment from 2005 through 2019, genuine NGK parts, direct replacement use, and a 1.1-millimeter gap.

Genuine NGK Iridium IX plugs arrive as a six-piece set for the Frontier’s 4.0L V6 from 2005 through 2019. That engine-specific coverage gives owners a clearly identified replacement option, while the included original packaging and hardware support a straightforward parts handoff during a scheduled plug service.

The listing identifies a direct-replacement set for the 4.0L V6 Frontier and names compatibility across model years 2005–2019, helping narrow the application before purchase. Iridium core material and a 1.1 mm gap are specified, giving buyers concrete plug details to compare with their service requirements. Six plugs are included for the V6 application, and the listing says original packaging and hardware come with them. The stated vehicle coverage does not extend to the 2.5L L4 Frontier.

Skip it if you own a 2.5L L4 Frontier; the Sixity Auto NGK Iridium IX B0DS1JB4H2 lists that engine instead.

Choose this set if your Frontier has the listed 4.0L V6 and you want six genuine NGK Iridium IX plugs with hardware included. Its stated Frontier range is 2005–2019, but it is not the L4 application.

#2 · Best 2.5L L4 Fit

2. Sixity Auto NGK Iridium IX L4

• Core Material: Iridium
• Top Material Type: Iridium
• Compatible with Vehicle Type: Car, Truck
• Gap Size: 0.04 in

Best for: Four-plug set for 2.5L L4.

Why it ranks #2: Unlike the V6-specific sets, this four-plug NGK iridium listing explicitly fits the Frontier 2.5L L4 from 2005 through 2019.

This four-piece NGK Iridium IX set specifically lists the Frontier 2.5L L4 for 2005–2019, separating it from the many 4.0L V6 choices. Genuine NGK parts, original packaging, and hardware are named, giving owners of the listed four-cylinder application a clearly defined replacement set.

The four-plug quantity aligns with the product’s stated 2.5L L4 application, and the listed Frontier range runs from 2005 through 2019. Iridium core and top materials identify the plug construction, while the 0.04-inch gap offers a concrete specification for comparison. The listing calls the plugs direct replacements and says original packaging and hardware are included. Its engine-specific scope is useful for L4 owners but does not make it the six-plug V6 option.

Skip it if you have a 4.0L V6 Frontier; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists that engine and its six-plug set.

Choose this for a Frontier 2.5L L4 within the listed 2005–2019 range when you want a four-piece NGK Iridium IX set. Its application is distinct from the 4.0L V6 listings.

#3 · Laser Iridium Pick

3. Sixity Auto NGK Laser Iridium

Best for: Laser Iridium for later V6 years.

Why it ranks #3: This six-plug genuine NGK Laser Iridium set specifies Frontier 4.0L V6 compatibility from 2007 through 2019.

NGK Laser Iridium plugs are listed for the Frontier 4.0L V6 from 2007 through 2019, giving later-model V6 owners a specifically named plug line. The six-piece set includes original packaging and hardware, and its direct-replacement description supports a defined replacement-parts workflow.

The application listing starts at 2007 and runs through 2019 for the Frontier 4.0L V6, making the year range especially important for owners of earlier trucks. Six plugs are supplied, with original packaging and hardware listed as included. NGK Laser Iridium is the named product line, but this listing provides no gap, thread, or core-material specification in the supplied details. That makes its stated engine and year coverage the main basis for evaluating this set.

Skip it if you own a 2005 or 2006 4.0L V6 Frontier; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists coverage beginning in 2005.

This is a fit to consider for a 2007–2019 Frontier 4.0L V6 when you want NGK Laser Iridium plugs in a six-piece set. Its stated year range excludes 2005 and 2006 trucks.

#4 · Performance Electrode

4. Sixity Auto DENSO Iridium Power

• Core Material: Iridium
• Top Material Type: Iridium
• Compatible with Vehicle Type: Car, Truck
• Gap Size: 0.04 in

Best for: Fine-electrode iridium option.

Why it ranks #4: The six-plug DENSO iridium set lists 4.0L V6 Frontier fitment for 2005–2016 and describes a 0.4-millimeter center electrode.

DENSO’s 0.4 mm iridium center electrode and tapered-tip design distinguish this six-plug set for the Frontier 4.0L V6, listed for 2005–2016. DENSO says its larger spark translates to more power and fuel economy, making the electrode design relevant to buyers considering a performance-oriented replacement.

The 0.4 mm center electrode and tapered tip are specific construction details that give this DENSO Iridium Power plug its stated design identity. Its U-Groove ground electrode is another named feature, while the six-piece set and listed 2005–2016 4.0L V6 Frontier fitment help define the intended service job. DENSO describes a larger spark as translating to more power and superior fuel economy; those are manufacturer claims, not guarantees for every vehicle or driving condition.

Skip it if you have a 2017–2019 4.0L V6 Frontier; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists coverage through 2019.

Consider these for a 2005–2016 Frontier 4.0L V6 if DENSO’s small iridium electrode and tapered-tip design suit your replacement preference. The stated Frontier range stops at 2016, so later models fall outside it.

5. IFATRUNK Iridium Spark Plugs

• Core Material: Iridium
• Top Material Type: Iridium
• Compatible with Vehicle Type: Car, Truck, Van
• Gap Size: 0.04 in

Best for: Broad V6 application coverage.

Why it ranks #5: This six-plug iridium set lists 4.0L V6 Frontier compatibility from 2005 through 2019 and includes a one-year manufacturer warranty.

A six-plug iridium set lists the Frontier’s 4.0L V6 alongside several Nissan, Infiniti, and Toyota applications. That broad reference coverage can help owners comparing replacement options across vehicles, while the 0.04-inch gap and multiple cross-reference numbers provide specific details for checking the intended plug application.

For Frontier owners, the supplied fitment covers 2005–2019 V6 4.0L models, and the six-plug count corresponds to that V6 listing. Iridium core material and a 0.04-inch gap give buyers specifications to compare with their application needs. The long reference-number list can also assist when matching an existing plug designation, although the range spans different vehicles and engines. This is a multi-application listing rather than a Frontier-only set, so its fitment details warrant careful attention.

Skip it if you want a Frontier-only listing; Sixity Auto’s NGK Iridium IX B0827YPXQ2 names the 4.0L V6 application directly.

This set suits buyers who value broad cross-vehicle reference coverage and have a Frontier 4.0L V6 within the listed years. Check the engine and reference details carefully; the listing also covers many other vehicles.

Listed on Amazon as: Iridium Spark Plugs 6 Pack Compatible with Nissan 350Z Altima Maxima Murano Xterra Pathfinder Frontier Quest, Infiniti G35 FX35 M35 I35, Toyota 4Runner Tundra, V6 2.7L-4.0L, Replaces 4469, LFR5AIX11

6. A-Premium Iridium Platinum

• Core Material: Platinum
• Top Material Type: Iridium
• Compatible with Vehicle Type: Car
• Gap Size: 0.04 in

Best for: Multi-vehicle iridium-platinum set.

Why it ranks #6: The six-plug set lists 4.0L V6 Frontier fitment from 2005 through 2019 and specifies platinum core material with an iridium top material.

A six-piece iridium-platinum set covers the Frontier 4.0L V6 for 2005–2019 while also listing applications across Nissan, Kia, and Toyota vehicles. Its broad coverage can help buyers sourcing plugs for more than one vehicle, and the 14 mm thread and 0.04-inch gap provide useful specification checks.

A six-plug quantity and stated Frontier 4.0L V6 coverage from 2005–2019 make this relevant to the listed V6 service. A platinum core with an iridium top combines the two materials named in the specifications, while the 14 mm thread and 0.04-inch gap give buyers details to compare with their application. The fitment list extends across multiple makes and engines, so the breadth can support parts research but requires attention to the exact vehicle entry.

Skip it if you want a Frontier-only product listing; Sixity Auto’s NGK Laser Iridium B0827Z37FV names the 4.0L V6 Frontier directly.

This suits buyers seeking a six-piece iridium-platinum set with broad listed vehicle coverage and a Frontier 4.0L V6 application. Match the precise vehicle entry and specifications because the listing spans multiple makes and engines.

Listed on Amazon as: A-Premium 4469 Iridium Platinum Spark Plugs (Pack of 6) Compatible with Nissan, Kia, Toyota Cars – Altima, Optima, Tundra, Santa Fe, 4Runner, Murano, Pathfinder, Maxima, Xterra, 2.7L-4.0L, 2001-2021

#7

7. Sixity Auto NGK G-Power

• Core Material: Copper
• Top Material Type: Iridium or Platinum
• Compatible with Vehicle Type: Car, Truck
• Gap Size: 0.04 in

Best for: NGK G-Power for Frontier V6.

Why it ranks #7: This six-plug genuine NGK set specifies 4.0L V6 Frontier fitment from 2005 through 2019, with a listed 0.04-inch gap.

NGK G-Power plugs are listed as a six-piece direct-replacement set for the Frontier 4.0L V6 from 2005 through 2019. The copper core and 0.04-inch gap distinguish the specifications, while included original packaging and hardware give the replacement parts a clearly identified set configuration.

The listed 2005–2019 Frontier 4.0L V6 coverage and six-plug quantity identify the intended service application. NGK G-Power is the named plug line, and the specifications state a copper core, M14x1.25 thread, and 0.04-inch gap, giving buyers concrete details for comparison. The direct-replacement description and included hardware support a parts replacement workflow, though the supplied information does not identify an operating-life interval or a performance gain for this plug.

Skip it if you specifically want iridium plugs; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists an iridium core for the same 4.0L V6 years.

Choose this if you want a six-plug NGK G-Power set for a listed 2005–2019 Frontier 4.0L V6 and value its specified thread and gap. Its copper core differs from iridium alternatives.

8. Sixity Auto DENSO Platinum TT

• Core Material: Platinum
• Top Material Type: Platinum
• Compatible with Vehicle Type: Truck
• Gap Size: 0.04 in

Best for: Platinum twin-tip V6 set.

Why it ranks #8: The six-plug DENSO platinum set lists 4.0L V6 Frontier compatibility from 2005 through 2016 and specifies platinum core and top materials.

DENSO Platinum TT plugs pair a 1.1 mm platinum center electrode with a titanium-enhanced ground strap in a six-piece set for Frontier 4.0L V6 models listed through 2016. DENSO associates its design with faster starts and a larger spark, offering a specific alternative to iridium plugs.

The twin-tip design combines a platinum center electrode and titanium-enhanced ground strap, while the specified 1.1 mm center electrode gives the construction a concrete point of comparison. DENSO describes faster starts and says a larger spark translates to more power and superior fuel economy; these are stated product claims, not guaranteed results. Six plugs are listed for the Frontier 4.0L V6 from 2005–2016, so later-year owners should note the stated application boundary.

Skip it if you have a 2017–2019 4.0L V6 Frontier; Sixity Auto’s NGK G-Power B084LFNGGM lists those years.

Consider this DENSO set for a 2005–2016 Frontier 4.0L V6 if the platinum twin-tip construction and stated starting benefits appeal. Its listed Frontier range ends in 2016, so it does not cover later models.

9. NGK LFR5AIX-11 Iridium IX

• Core Material: Iridium
• Top Material Type: Iridium
• Compatible with Vehicle Type: Car, Truck
• Gap Size: 0.04 in

Best for: Eight-plug NGK iridium set.

Why it ranks #9: This listing offers eight NGK iridium plugs and a 0.04-inch gap, but instructs buyers to research vehicle applications before purchasing.

NGK supplies eight Iridium IX plugs in this listing, a useful quantity for buyers whose intended service requires more than the six plugs specified by many Frontier V6 sets. The 14 mm thread and 0.04-inch gap add concrete specifications, but the listing calls for application research before purchase.

The eight-plug quantity is the clearest distinction here: it gives buyers a larger set than the six-piece Frontier V6 listings, though the required quantity depends on the vehicle and service. NGK identifies iridium core and top materials, a 14 mm thread, and a 0.04-inch gap, helping shoppers compare plug specifications. The listing presents model 4469 and LFR5AIX-11 but does not name a Frontier fitment, and it explicitly advises researching the application, engine, drivetrain, and quantity needed.

Skip it if you need an explicitly listed Frontier 4.0L V6 application; Sixity Auto’s NGK Iridium IX B0827YPXQ2 names that fitment.

This set may suit buyers who need NGK Iridium IX plugs in an eight-piece quantity and can verify the application from the supplied model and specifications. The product page does not identify a Frontier engine fitment.

#10

10. ENA Platinum Spark Plugs

• Core Material: Platinum
• Top Material Type: Platinum
• Compatible with Vehicle Type: Nissan Frontier, Nissan Versa Note, Nissan…
• Gap Size: 0.04 in

Best for: Platinum plugs for 2.5L L4.

Why it ranks #10: The four-plug platinum set lists Frontier 2.5L fitment, but its title limits Frontier years through 2017 while its features extend through 2019.

ENA’s platinum set is listed for the Frontier’s 2.5L L4 across 2005–2019, making it the four-cylinder-focused option in this group. Four plugs are included, and the listing also covers several other Nissan four-cylinder applications, which can help buyers comparing parts for multiple vehicles.

The platinum core and top material distinguish this set from the iridium options, while the 0.04-inch gap and 12.00 mm thread provide specifications for an application check. ENA lists Frontier 2.5L L4 coverage from 2005 through 2019 and supplies four plugs, aligning the set with the stated four-cylinder application. The additional Sentra, Versa, Versa Note, Micra, and Suzuki Equator coverage may be useful for multi-vehicle parts planning, but this is not the listed 4.0L V6 option.

Skip it if you own a 4.0L V6 Frontier; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists that engine and a six-plug set.

Pick these if your Frontier is the listed 2.5L L4 and you want a four-piece platinum set with specified thread and gap dimensions. The fitment is for the L4, not the 4.0L V6.
