#2 · Laser Iridium Pick

2. Sixity Auto NGK Laser Iridium

Best for: 2007–2019 Laser Iridium set.

Why it ranks #2: The six-plug listing specifically fits the Frontier 4.0L V6 from 2007–2019 and identifies the plugs as genuine NGK parts.

NGK Laser Iridium coverage begins with 2007 Frontier 4.0L V6 models and extends through 2019, a useful year-range distinction among the listed six-plug sets. The package includes six genuine NGK plugs, original packaging, and hardware for owners matching that engine and application.

The specific 2007–2019 Frontier 4.0L V6 range helps owners identify whether this Laser Iridium set corresponds to their truck, while six plugs provide the listed set quantity. NGK identification and the Laser Iridium name distinguish its plug type from the G-Power and Iridium IX listings.

#3 · Ruthenium Option

3. Sixity Auto NGK Ruthenium HX

Best for: 2005–2019 Ruthenium HX set.

Why it ranks #3: This six-plug NGK set is listed for the 2005–2019 Frontier 4.0L V6 and includes original packaging and hardware.

NGK Ruthenium HX is the defining plug type in this six-piece set, which lists Frontier 4.0L V6 compatibility across 2005–2019. That broad stated model-year span gives owners a clearly identified application window for considering a full-set replacement.

The listing names NGK Ruthenium HX plugs and covers Frontier 4.0L V6 models from 2005 through 2019, so buyers can assess the stated engine and year range directly. Six plugs provide the listed quantity for the V6 application, and the product is described as a direct replacement with hardware included. Those details support a coordinated maintenance purchase. The supplied specifications do not state a thread size or gap, so shoppers should not infer those measurements from the model name alone.

Skip it if you need the thread size and gap stated in the listing; NGK 4469 Iridium IX B00330AMYS provides both measurements.

Choose this set if your Frontier is a 2005–2019 4.0L V6 and you want the listed NGK Ruthenium HX type in a six-plug quantity. The supplied details leave thread and gap measurements unspecified.

#4 · DENSO Iridium Pick

4. Sixity Auto DENSO Iridium Power

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

Best for: Earlier 4.0L V6 Iridium Power.

Why it ranks #4: The six-plug DENSO set is listed for 2005–2016 Frontier 4.0L V6 models and specifies a 0.04-inch gap and iridium core.

DENSO’s 0.4mm iridium center electrode and tapered-tip Iridium Power design are the key differentiators in this six-plug set. The listed Frontier coverage runs from 2005 through 2016 for the 4.0L V6, giving owners of those model years a defined DENSO option.

The six-plug quantity matches the listed Frontier V6 application, while the 2005–2016 fit range sets a clear boundary for shoppers. DENSO names a tapered-cut U-Groove ground electrode and a 0.4mm iridium center electrode, details that distinguish the Iridium Power construction. The listing says a larger spark translates to more power and superior fuel economy; those are manufacturer claims, not guarantees for every vehicle. A 0.04-inch gap is also specified for comparison with service needs.

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

A fit for owners of a 2005–2016 Frontier 4.0L V6 who want DENSO Iridium Power construction in a six-plug set. Its stated model-year range stops at 2016, so later Frontiers fall outside this listing.

5. Sixity Auto NGK G-Power

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

Best for: 4.0L V6 G-Power replacement.

Why it ranks #5: Its six genuine NGK plugs are listed for the 2005–2019 Frontier 4.0L V6, with a 0.04-inch gap and original packaging.

This six-plug NGK G-Power set explicitly covers Nissan Frontier 4.0L V6 models from 2005 through 2019, making its application easy to compare with the truck’s engine and year. The listing calls the plugs direct replacements and includes hardware, supporting a coordinated replacement-parts purchase.

The stated 2005–2019 Frontier 4.0L V6 coverage gives owners a defined application window, and six plugs provide a complete set for that listed V6. NGK G-Power identification distinguishes this option from the Iridium IX alternatives in the supplied range. Included hardware and the direct-replacement description are practical details when assembling parts for maintenance. The listing also specifies an M14x1.25 thread and a 0.04-inch gap, useful measurements to compare with service requirements.

Skip it if you want an iridium-core option; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists the same Frontier 4.0L V6 model-year range.

This is a sensible match for owners servicing a 2005–2019 Frontier 4.0L V6 who want the listed NGK G-Power type and a six-plug set. Its specified core material is copper, not iridium.

6. NGK 4469 Iridium IX

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

Best for: Iridium IX six-plug set.

Why it ranks #6: This six-pack lists iridium construction, a 0.04-inch gap, and 14mm-1.25mm thread size, but its title does not specify Frontier fitment.

A fine-wire iridium center electrode is the defining feature of NGK’s six-pack 4469 Iridium IX plugs, giving buyers a performance-oriented electrode design in a set of six. The listing also specifies fuel-injected and turbo engines, making those applications part of its stated use rather than an assumed benefit.

The fine-wire iridium center electrode and precision laser electrode construction describe how this plug is made, while the nickel-alloy ground electrodes complete the listed electrode materials. NGK specifically says the plugs are designed for fuel-injected and turbo engines, a useful application detail for shoppers comparing plug types. The six-pack quantity supports a multi-plug service, and the listed 14mm-1.25mm thread and 0.04-inch gap give concrete specifications to check against the vehicle’s requirements.

Skip it if you want a Frontier-specific fit listing; Sixity Auto’s NGK Iridium IX B0827YPXQ2 names the 4.0L V6 and 2005–2019 models.

Consider this NGK set if its 4469 specifications and fuel-injected or turbo application match your vehicle. For a Frontier purchase, the listing leaves year and engine fit unspecified, so it is not a model-specific choice.

• Core Material: Iridium

• Gap Size: 0.04 in

Best for: Multi-model iridium plug set.

Why it ranks #7: The six-pack explicitly lists compatibility with the 2005–2019 Frontier 4.0L V6 and gives a 0.04-inch gap, though it is a non-NGK set.

The IFATRUNK six-pack lists the 2005–2019 Nissan Frontier 4.0L V6 among a broad set of compatible vehicles, giving buyers a multi-model iridium option. Its listed references include 4469 and LFR5AIX-11, useful identifiers when comparing replacement-plug specifications across the stated applications.

For Frontier shoppers, the explicit 2005–2019 4.0L V6 compatibility and six-plug quantity make the intended set straightforward to assess. The iridium core and 0.04-inch gap are further listed specifications that can be checked against the vehicle’s service needs. The product also names applications for several other Nissan and Infiniti models, which may be useful when one parts order covers multiple vehicles. Its stated reference numbers help identify the plug family, but do not replace application checks.

Skip it if you prefer a set identified specifically as genuine NGK; Sixity Auto’s NGK Iridium IX B0827YPXQ2 lists the same Frontier V6 range.

This set suits buyers seeking six iridium plugs for a listed Frontier 4.0L V6, especially if they also service another named application. Check the exact vehicle listing and specifications before choosing among its broad fit range.

8. Sixity Auto DENSO Platinum TT

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

Best for: Frontier platinum twin-tip set.

Why it ranks #8: This six-plug platinum set is listed for the 2005–2016 Frontier 4.0L V6, but its stated fitment range is shorter than several alternatives.

DENSO Platinum TT uses a 1.1mm platinum center electrode and twin-tip construction, making its electrode design the main point of distinction. This six-plug set lists Nissan Frontier 4.0L V6 compatibility from 2005 through 2016, targeting owners within that stated model-year range.

The Platinum TT name and listed platinum core identify the plug material, while the product description specifies a platinum center electrode and titanium-enhanced ground strap. DENSO calls this Twin-Tip Technology and associates its plugs with faster starts; that claim comes from the listing rather than a vehicle-specific guarantee. Six plugs match the stated V6 application quantity, and the 0.04-inch gap gives a specification to compare with maintenance requirements. The listed Frontier range ends in 2016.

Skip it if you own a 2017–2019 Frontier 4.0L V6; Sixity Auto’s NGK Laser Iridium B0827Z37FV lists those years.

Consider this set for a 2005–2016 Frontier 4.0L V6 when you want DENSO Platinum TT construction and six plugs. Its stated coverage does not extend to 2017–2019 models.

9. NGK 4469 Iridium IX 8-Pack

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

Best for: Eight-plug NGK Iridium IX pack.

Why it ranks #9: It lists iridium construction and a 0.04-inch gap, but the eight-plug quantity exceeds the six-plug sets listed for the 4.0L V6.

Eight NGK Iridium IX plugs distinguish this pack from the six-piece Frontier V6 sets, making quantity the first detail to weigh. NGK describes the plugs as often specified for original equipment and emphasizes performance and longevity, while the listed iridium core supplies a clear material specification.

The eight-plug quantity may suit a buyer whose application or service plan calls for that number, but it differs from the six-plug sets listed specifically for Frontier V6 engines. NGK identifies the 4469 LFR5AIX-11 model and a 0.04-inch gap, giving shoppers concrete details to compare with vehicle requirements. Its iridium core and OEM-oriented description help identify the plug category, although the product listing advises researching application, drivetrain, engine, and quantity before purchase.

Skip it if you need a six-plug Frontier set; Sixity Auto’s NGK Iridium IX B0827YPXQ2 specifies the 4.0L V6 application and six-plug quantity.

Choose this pack only when eight plugs and the 4469 Iridium IX specification suit your application. Frontier owners should weigh its quantity against the six plugs specified for the listed V6 sets.

10. Sixity Auto NGK Iridium IX 2.5L

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

Best for: 2.5L L4 four-plug set.

Why it ranks #10: This genuine NGK four-pack is listed for the 2005–2019 Frontier 2.5L L4, not the more common 4.0L V6 application represented here.

This four-plug NGK Iridium IX set is specifically listed for Nissan Frontier 2.5L L4 models from 2005 through 2019, distinguishing it from the 4.0L V6 sets. Its engine-specific application and four-piece quantity give owners of the listed four-cylinder Frontier a focused replacement option.

The 2.5L L4 designation and 2005–2019 Frontier year range define the stated application, while four plugs match the quantity supplied for that engine listing. NGK Iridium IX identification and the listed iridium core specify the plug type and material. The product is described as a direct replacement and includes hardware, which can help organize a scheduled plug service. A 0.04-inch gap is specified; use the vehicle’s requirements when assessing the application.

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

This is the focused choice for owners of a 2005–2019 Frontier 2.5L L4 who need four NGK Iridium IX plugs. Its stated engine application does not cover the 4.0L V6.
