• Compatible with Vehicle Type: Truck
• Gap Size: 0.03 in

Best for: 2016–2020 3.5L V6 owners.

A six-plug Champion Iridium set listed specifically for Tacoma 3.5L V6 models from 2016–2020 makes this one of the roundup’s directly relevant third-generation options. Its 10mm thread and 0.03-inch gap are useful specifications to weigh when planning a replacement.

The six-piece quantity aligns with the listing’s 3.5L V6 application, and the specified 10mm thread and 0.03-inch gap give concrete installation details. Champion describes its plugs as using durable precious metals for long-lasting, powerful performance, while the iridium core identifies the stated center material. The fitment list covers Tacoma model years 2016–2020; it does not establish coverage beyond that range, so later trucks fall outside the supplied application information.

#3 · Broad V6 Coverage

3. E3 Spark Plugs V6

Best for: V6 owners seeking DiamondFIRE.

Why it ranks #3: The six-pack listing names Tacoma 3.5L and 4.0L V6 engines and claims coverage across a broad range of model years, though fit should be verified.

E3’s DiamondFIRE edge-to-edge spark path is the defining feature of this six-plug set, which is listed for Tacoma 3.5L and 4.0L V6 models across 2005–2022. That broad stated range makes it relevant to several V6 generations, subject to its listed engine applications.

The edge-to-edge spark path is described as allowing fresh charge to replenish the spark zone, connecting the DiamondFIRE design to its stated ignition function. E3 also says the plugs are intended to increase power and reduce fuel consumption, while an included resistor reduces electromagnetic interference. Six plugs suit the listed V6 applications, and the Tacoma fitment spans 2005–2022 for 3.5L and 4.0L V6 engines; the listing does not name the 2.7L L4.

Skip it if you own a 2.7L L4; E3 Spark Plugs set B0D1LKYWBQ lists Tacoma 2.7L L4 applications.

Consider this E3 set for a Tacoma V6 within the stated 2005–2022 3.5L or 4.0L applications, especially if DiamondFIRE’s spark path matters. It is not listed for four-cylinder trucks.

#4 · Broad L4 Coverage

4. E3 Spark Plugs 2.7L

Best for: 2.7L L4 DiamondFIRE users.

Why it ranks #4: This four-pack is listed for the Tacoma 2.7L L4 across a broad model-year range and describes E3's DiamondFIRE electrode design.

E3’s DiamondFIRE edge-to-edge spark path distinguishes this four-plug set for Tacoma 2.7L L4 models listed from 2005–2022. The broad year span reaches well into the third generation, making its stated four-cylinder application the key selection detail.

The edge-to-edge spark path is described as replenishing the spark zone with a fresh charge, which links the design to its stated ignition workflow. E3 says the plug is intended to increase power and reduce fuel consumption, and its resistor is included to reduce electromagnetic interference. Four plugs match the listed 2.7L L4 application, with Tacoma fitment stated across 2005–2022; the product is not listed for V6 engines.

5. DENSO Iridium Power 2.7L

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

Best for: 2.7L four-cylinder owners.

Why it ranks #5: The four-pack fits the Tacoma 2.7L L4, but its stated fit range includes only part of the third-generation period; it lists a 0.04-inch gap.

This four-piece DENSO Iridium Power set is listed for Tacoma 2.7L L4 models from 2005–2016, including the first year of the third generation. Its 0.4mm iridium tip and U-Groove electrode distinguish the design from a basic replacement plug.

The four-plug quantity corresponds to the listed 2.7L L4 application, and the fine 0.4mm iridium tip paired with a tapered-cut U-Groove electrode provides specific construction details. DENSO associates its larger spark with power and fuel-economy benefits, offering a stated performance rationale for the design. The product information lists a 0.04-inch gap and Tacoma coverage through 2016, but does not extend the stated fitment to later third-generation years.

Skip it if you need 2017–2020 2.7L L4 coverage; NGK Laser Iridium set B0F1GVM255 lists those Tacoma years.

This DENSO set suits a listed 2005–2016 Tacoma 2.7L L4 replacement where its iridium tip and U-Groove design appeal. Buyers with later third-generation trucks need an application listing that covers those years.

6. Toyota Genuine Spark Plug

• Core Material: Copper
• Top Material Type: Nickel
• Compatible with Vehicle Type: Cruiser

Best for: Toyota OEM replacement buyers.

Why it ranks #6: This genuine Toyota replacement listing includes Tacoma fitment but does not identify the engine or plug count, making exact third-generation matching less clear.

Toyota’s genuine OEM replacement identity is the defining feature of this spark plug, making it a direct option for owners prioritizing a Toyota-branded part. The listed Tacoma coverage runs from 2005 through 2014, however, so it does not establish fitment for third-generation Tacoma models.

The listing names Tacoma models from 2005–2014, alongside several other Toyota vehicles, which helps buyers identify its intended older applications. Toyota specifies a 14mm thread and copper core with a nickel top, offering concrete details for a replacement decision. Its singular product title and lack of a stated engine size mean the supplied information does not establish a complete set quantity or confirm a particular Tacoma engine configuration.

Skip it if you need listed 2016-or-newer Tacoma coverage; NGK Laser Iridium set B0F1GVM255 lists 2016–2020 2.7L L4 applications.

This Toyota genuine plug suits buyers seeking an OEM-branded replacement for a Tacoma within the stated 2005–2014 range. The listing does not specify engine size or quantity, and its years do not cover third-generation models.

7. DENSO Iridium Power 4.0L

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

Best for: 4.0L V6 performance focus.

Why it ranks #7: Its six-pack and 0.044-inch listed application gap suit the 4.0L V6 listing, but that engine fitment does not target the third-generation Tacoma.

A 0.4mm iridium tip paired with DENSO’s tapered-cut, U-Groove ground electrode defines this Iridium Power set. It supplies six plugs for listed Tacoma 4.0L V6 models from 2005–2015, making its engine and year boundary important for third-generation shoppers.

The six-plug count corresponds to the stated Tacoma 4.0L V6 application, while the 0.4mm iridium tip and U-Groove ground electrode identify the plug’s construction. DENSO says the larger spark can translate to more power and superior fuel economy, connecting the electrode design to its stated performance aims. The additional description gives a 0.044 gap, but the listed vehicle coverage ends in 2015 rather than including third-generation model years.

Skip it if you need a 2016–2020 3.5L V6 application; Champion Iridium set B0B7KTCCSV lists those Tacoma years and engine.

This DENSO Iridium Power set fits the stated 2005–2015 Tacoma 4.0L V6 buyer seeking its fine iridium tip and U-Groove design. It is not listed for the later third-generation 3.5L V6.

8. DENSO Iridium Long Life 4.0L

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

Best for: 4.0L V6 long-life shoppers.

Why it ranks #8: The six-pack is explicitly for the 4.0L V6 and describes an iridium long-life plug, but the listed engine application is not the target generation.

DENSO’s Iridium Long Life formulation, including a 0.4mm iridium center electrode and platinum ground strap, is the key distinction here. The six-plug set is listed for 2005–2015 Tacoma 4.0L V6 models, not the later 3.5L V6 introduced for third-generation trucks.

A six-piece set matches the listed 4.0L V6 application, and DENSO’s fine-wire 0.4mm iridium center electrode gives the design a clearly specified ignition feature. The additional platinum ground strap is identified in the product description as part of its Iridium Long Life construction. DENSO also links a larger spark with power and fuel-economy benefits; the supplied fitment details, however, stop at 2015 and specify a 0.044 gap in the additional description.

Skip it if you own a 2016–2020 3.5L V6; the Champion Iridium set lists that Tacoma engine and year range.

Consider this DENSO set when replacing plugs on a listed 2005–2015 Tacoma 4.0L V6 and prioritizing its iridium-and-platinum construction. Its supplied fitment does not extend to the third-generation 3.5L V6.

9. NGK Iridium IX 4.0L

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

Best for: Older 4.0L V6 owners.

Why it ranks #9: This six-pack names the Tacoma 4.0L V6 and lists an iridium core, but its stated vehicle application does not match the target generation.

Iridium construction and a six-plug set make this NGK Iridium IX option relevant to Tacoma 4.0L V6 owners handling a full plug replacement. Its listed application is limited to 2005–2015 trucks, so it is not presented as a fit for the third-generation 3.5L V6.

The six-plug quantity suits the listed 4.0L V6 application, while the iridium core and top identify the electrode material. NGK describes the plug as helping reduce misfires and emissions and support fuel economy, giving buyers a specific reason to consider it beyond routine replacement. Its stated 14mm thread and 0.04-inch gap provide installation specifications, but the supplied Tacoma fitment ends before the 2016 model year.

Skip it if you have a 2016-or-newer 3.5L V6; the Champion Iridium set lists Tacoma 2016–2020 fitment.

Choose this six-piece NGK set for a listed 2005–2015 Tacoma 4.0L V6 replacement where iridium construction matters. Its application does not cover the later third-generation Tacoma engines listed in this roundup.

10. NGK Laser Iridium 2.7L Earlier Fit

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

Best for: Older 2.7L L4 replacements.

Why it ranks #10: Although its four-pack is for the 2.7L L4 and has an iridium core, its listed fitment ends before the third-generation application.

NGK Laser Iridium construction comes in a four-plug set listed for Tacoma 2.7L L4 models from 2005–2015. That makes it an older four-cylinder replacement option, but its stated years do not extend into the third-generation Tacoma range.

The four-plug quantity is matched to the listing’s 2.7L L4 application, and the iridium core identifies its electrode material. NGK marks the parts as genuine and the listing identifies them as direct replacement auto parts, details that help frame a like-for-like service choice. A 14mm thread and 0.04-inch gap are also specified. The stated Tacoma coverage ends at 2015, so the listing does not establish fitment for third-generation 2.7L models.

Skip it if you have a 2016–2020 2.7L L4; NGK Laser Iridium set B0F1GVM255 lists those Tacoma years.

This four-piece NGK set suits buyers replacing plugs on a listed 2005–2015 Tacoma 2.7L L4. Its genuine Laser Iridium construction is specific, but the supplied application does not cover later third-generation trucks.
