A strong choice for a Dodge Challenger V6 is a six-plug set whose listed engine and model-year fitment matches your car, with the electrode type and gap checked against its service information. The NGK Laser Iridium set is a leading candidate for 3.6L V6 Challengers from 2011 through 2020; owners of other years or the 3.5L engine need to compare fitment carefully. This roundup covers seven sets, including several NGK designs, a DENSO Iridium Power option, and XP5701-style alternatives.
Their coverage differs: some list a specific Challenger engine and year range, while others span multiple vehicles. Use the exact engine, year, and required plug specification to narrow the choices, and confirm fitment before ordering rather than relying on the broad V6 keyword alone.
For a 3.6L V6 Challenger listed from 2011 through 2020, NGK Laser Iridium is the lead choice: its product data specifies a six-plug set, iridium center material, and a 0.04-inch gap, alongside direct-replacement positioning and genuine NGK parts. It covers the broad model-year range shared by several contenders while stating the material and gap. Confirm the exact vehicle fitment and plug specification before ordering; this listing does not cover the separately listed 3.5L Challenger from 2009–2010.

Why it ranks #3: Lists six genuine NGK plugs for 3.6L V6 Challengers from 2011 through 2020 and includes original packaging and hardware.
Genuine NGK G-Power plugs are supplied as a six-piece set for the Challenger 3.6L V6 across the listed 2011–2020 years. That specific NGK line and broad application give owners a direct-replacement option, with original packaging and hardware included in the listing.
The six-plug count makes this a complete set as presented for the listed V6 application, and the direct-replacement description supports a standard replacement workflow. NGK identifies the plugs as genuine G-Power parts, while the compatibility details cover Challenger 3.6L V6 models from 2011 through 2020. Original packaging and hardware are included.

View on Amazon#4 · Best for 2013–2016 Fitment
4. DENSO Iridium Power
- Core Material: Platinum
- Compatible with Vehicle Type: Car, Truck
Best for: 2013–2016 Iridium Power option.
Why it ranks #4: Specifically lists 3.6L V6 Challenger fitment for 2013–2016 and describes a 0.4mm iridium tip, though the specification field says platinum.
DENSO’s 0.4 mm iridium center electrode and tapered-tip design distinguish this six-plug Iridium Power set for 2013–2016 Challenger 3.6L V6 models. The listing connects those electrode features with a larger spark, making it an option for owners seeking DENSO’s stated performance-oriented plug design.
The tapered-cut ground electrode and U-Groove design give this plug specific electrode geometry, while the 0.4 mm iridium tip is identified as the world’s smallest center electrode in the supplied description. DENSO states that a larger spark translates to more power and superior fuel economy; those are manufacturer claims, not guaranteed results for every vehicle. The listed Challenger fitment is limited to 2013–2016 3.6L V6 models, so the year and engine range matters when choosing this set.
- Six DENSO Iridium Power plugs
- 0.4 mm iridium tip
- Tapered-cut ground electrode
- U-Groove design; listed for 2013–2016 Challenger 3.6L V6
- Listed Challenger fitment covers only 2013–2016 3.6L V6 models.
Skip it if you need coverage for a 2011–2020 3.6L V6 Challenger; the Sixity Auto NGK Laser Iridium set B0B7KRPQM5 lists that broader range.
Consider this DENSO set if your Challenger is a listed 2013–2016 3.6L V6 and you want its small iridium tip and specified electrode design. The fitment range is narrower than some Challenger listings.

5. A-NAFTULY XP5701
- Core Material: Iridium
- Top Material Type: Iridium
- Compatible with Vehicle Type: Car, Truck, Van
- Gap Size: 0.04 in
Best for: Broad multi-vehicle XP5701 set.
Why it ranks #5: Lists XP5701 references and 3.6L Challenger fitment from 2011 through 2021, with iridium material, a 0.040-inch gap, and a 12-month warranty.
A six-pack of XP5701 iridium plugs lists Challenger 3.6L V6 fitment from 2011 through 2021, one year beyond several Challenger-specific options here. Its stated compatibility also spans numerous Dodge, Chrysler, Jeep, and Ram vehicles, which can suit owners maintaining more than one listed application.
The listed 0.04-inch gap and 12 mm thread size provide concrete dimensions for checking this plug against the intended application, while the 5/8-inch hex size describes the tool interface. Six plugs are included, and the stated Challenger range runs 2011–2021 for the 3.6L V6. The fitment list also names other vehicles, including the Charger, Durango, Grand Caravan, and Jeep Grand Cherokee, making this set relevant to owners working across those listed applications.
- Six iridium plugs included
- Listed for Challenger 3.6L V6, 2011–2021
- 0.04-inch gap
- 12 mm thread and 5/8-inch hex specifications
- The listing identifies the plugs by XP5701 and reference numbers, not as a named major-brand plug line.
Skip it if you prefer a named NGK line for a 2011–2020 Challenger 3.6L V6; the Sixity Auto NGK Laser Iridium set B0B7KRPQM5 lists that application.
This suits owners matching the XP5701 dimensions and broad listed vehicle coverage, especially those servicing more than one compatible model. Its Challenger listing ends at 2021, and buyers should use the stated application and dimensions when selecting plugs.

6. RLP XP5701
- Core Material: Iridium
- Top Material Type: Iridium
- Compatible with Vehicle Type: Car
- Gap Size: 0.03 in
Best for: Specified-gap XP5701 alternative.
Why it ranks #6: Lists a six-plug XP5701 set for 3.6L Challenger fitment from 2011 through 2021 and a one-year warranty, but its gap figures conflict.
A specified 0.034-inch gap and 0.6 mm center electrode set this six-plug iridium-and-platinum XP5701 listing apart. It names Challenger 3.6L V6 fitment for 2011–2021 and states a designed life of 60,000 kilometers, giving buyers concrete specifications to weigh for a replacement decision.
The listing pairs an iridium center tip with a platinum ground electrode, a material combination that distinguishes it from plugs described simply as iridium. Its 0.034-inch gap, 12 mm thread diameter, and 5/8-inch hex size provide dimensional details for checking against the intended service application. The six-piece set is listed for Challenger 3.6L V6 models from 2011–2021, and the stated 60,000-kilometer designed life offers a defined maintenance reference rather than an open-ended longevity promise.
- Six plugs included
- Iridium center electrode and platinum ground electrode
- 0.034-inch stated gap
- 12 mm thread; 60,000-kilometer designed life stated
- The stated designed life is 60,000 kilometers.
Skip it if you want a genuine NGK listing for a 2011–2020 Challenger 3.6L V6; the Sixity Auto NGK Iridium IX set B0F8FS69CZ covers those years.
A candidate for Challenger 3.6L V6 owners comparing electrode materials and a defined service-life figure. The listing specifies 2011–2021 fitment and 60,000 kilometers of designed life; match its stated gap and dimensions to the service application.

7. NGK Iridium IX 3.5L
- Compatible with Vehicle Type: Car, Truck
Best for: 2009–2010 3.5L V6 fitment.
Why it ranks #7: This six-plug genuine NGK set is specifically for the 3.5L V6 Challenger from 2009–2010, not the 3.6L fitment listed by most alternatives.
This six-piece NGK Iridium IX set targets a different Challenger application: the 3.5L V6 for model years 2009–2010. That specific older-engine fitment is its defining advantage for owners whose vehicle falls outside the newer 3.6L V6 ranges listed by other options.
The listing identifies genuine NGK Iridium IX plugs and describes them as direct replacement auto parts, supporting a conventional service choice for the stated application. Its six-plug quantity is supplied for the 3.5L V6, and the compatibility details specify Challenger model years 2009 and 2010. Original packaging and hardware are included. Unlike listings for later 3.6L V6 Challengers, this set’s stated fitment is centered on the earlier 3.5L engine and narrow year range.
- Six NGK Iridium IX plugs
- Genuine NGK parts stated
- Listed for Challenger 3.5L V6, 2009–2010
- Original packaging and hardware included
- Fitment is limited to 2009–2010 Challenger 3.5L V6 models.
Skip it if you have a 2011–2020 Challenger 3.6L V6; the Sixity Auto NGK Iridium IX set B0F8FS69CZ lists that newer engine and year range.
This is the application-specific pick for owners of a listed 2009–2010 Challenger 3.5L V6 seeking NGK Iridium IX direct replacements. Its fitment does not extend to the later 3.6L V6 models.

View on AmazonAvoid the engine-and-year fitment trap
The key compatibility trap is treating every Challenger V6 plug as interchangeable: the listings separate 3.6L applications from a 3.5L application. NGK Iridium IX 3.5L is listed for 2009–2010 Challengers with the 3.5L V6, while the other NGK Challenger sets here specify a 3.6L V6 from 2011 through A-NAFTULY XP5701 extends its stated 3.6L coverage through 2021, and DENSO Iridium Power lists only 2013–2016.
Those ranges are product-listing claims, not a substitute for checking the vehicle’s exact engine and year. Compare the listing with your vehicle information and the part number required for that application before ordering.
If a fitment checker or catalog result disagrees with the product title, resolve the discrepancy first; a matching brand or V6 description alone does not establish fit.
Check listed gap figures before installation
The listed gaps are not consistent across these products, so do not assume every set arrives at the specification your engine requires. NGK Laser Iridium and NGK Iridium IX each list 0.04 inches; A-NAFTULY XP5701 lists 0.040 inches, while RLP XP5701 gives 0.034 inches in its feature text and 0.03 inches in its specifications. DENSO Iridium Power does not provide a gap figure in the supplied specifications.
These differences make the vehicle’s required plug specification the deciding reference, not a generic preference for a smaller or larger gap. In particular, the two RLP figures disagree within the same listing, so verify the correct value with authoritative fitment information before installation.
The data here does not establish whether any plug should be adjusted or installed exactly as received.
How to Choose Challenger V6 Spark Plugs
Engine and model-year fitment
Look first for a listing that names your Challenger’s exact engine and model-year range. NGK Laser Iridium, NGK Iridium IX, and NGK G-Power each list 3.6L V6 fitment from 2011 through 2020; A-NAFTULY XP5701 lists 2011 through 2021, while DENSO Iridium Power covers 2013 through NGK Iridium IX 3.5L instead lists the 3.5L engine for 2009–2010.
These are meaningful distinctions, not interchangeable coverage. Choose a narrow range when it matches your car exactly, and do not stretch a listing’s range based on the Challenger name alone.
If your vehicle falls outside a stated range, verify the correct application before selecting a set.
Electrode material and listing detail
Check the listed electrode material, and note where product details conflict. NGK Laser Iridium and NGK Iridium IX identify iridium in their specifications; A-NAFTULY XP5701 also lists iridium. RLP XP5701 describes an iridium center and platinum ground electrode.
DENSO Iridium Power is described as having a 0.4mm iridium tip in its features, but its specification field says core material is platinum. That mismatch makes its listing less clear on material than the NGK options.
Buyers who want specifications stated consistently may prefer a listing with matching feature and specification details; those considering DENSO should confirm the exact product and application information rather than assuming the title resolves the discrepancy.
Gap specification
Compare the stated gap with the value required for your exact engine before buying or installing. NGK Laser Iridium and NGK Iridium IX specify 0.04 inches, and A-NAFTULY XP5701 lists 0.040 inches. RLP XP5701 lists 0.034 inches in its feature text but 0.03 inches in the specifications, so its own figures are inconsistent.
The DENSO specifications supplied here do not state a gap. For buyers whose service information calls for a value matching a clearly listed figure, the NGK or A-NAFTULY listings make comparison straightforward.
If the required gap differs, or a listing omits or conflicts on the value, verify the correct application and specification rather than selecting by gap alone.
Which Challenger V6 Spark Plugs Should I Choose?
For a 3.6L V6 Challenger listed from 2011 through 2020, choose NGK Laser Iridium for its stated fitment, iridium material, and 0.04-inch gap. If you specifically want the NGK Iridium IX design or G-Power line, NGK Iridium IX and NGK G-Power list the same 3.6L year span and include six plugs. For a 2013–2016 3.6L Challenger, DENSO Iridium Power is another fitment-specific option, but its material fields conflict.
A-NAFTULY XP5701 states coverage through 2021 and a 0.040-inch gap; RLP XP5701 has conflicting gap figures. For a 2009–2010 3.5L V6, consider only NGK Iridium IX 3.5L from this selection.
Confirm fitment and required specifications before purchase.

Frequently Asked Questions
How can I confirm the correct spark plug part number for my Challenger engine and model year?
Check your owner’s manual or confirm fitment with a Dodge parts department using your vehicle identification number (VIN). Match the engine size and model year, then verify the plug’s part number and required specifications before ordering. The listings include different 3.6L and 3.5L applications, so don’t rely on the Challenger name alone.
Should I replace all six spark plugs at the same time on a V6 Challenger?
Replacing all six together is a practical approach when the plugs are due, since the listed V6 sets contain six plugs. Confirm that the set fits your engine and model year first. If you’re addressing a single plug issue, follow your vehicle’s service guidance or ask a qualified technician whether replacement of all six is appropriate.
What symptoms can indicate worn or incorrectly gapped spark plugs?
Rough idling, misfires, difficult starting, hesitation, or reduced engine performance can indicate a spark plug problem, though other faults can cause similar symptoms. Have the plugs and ignition system checked before replacing parts. If a gap is specified, verify it against the vehicle’s required specification rather than assuming the listing’s gap is correct for your car.
How should I handle conflicting gap information between listings?
Verify the required gap in your vehicle’s service information, then compare it with the plug manufacturer’s specification for the exact part number. The RLP XP5701 listing has conflicting gap figures, so don’t choose or install it based on an uncertain listing value. Confirm the specification with the seller or manufacturer before ordering.
Which listed option is intended for a 2009–2010 3.5L V6 Challenger?
The NGK Iridium IX listing specifically identifies the 3.5L V6 Challenger from 2009–The other options are listed for 3.6L applications, so don’t assume they fit the 3.5L engine. Confirm the exact part number and vehicle fitment before purchase.
Final Words
For a 3.6L V6 Challenger listed from 2011 through 2020, the NGK Laser Iridium set is the lead choice because its listing states six plugs, iridium material, and a 0.04-inch gap. Verify the part number and required specification for your exact vehicle before ordering. For a 2009–2010 3.5L V6, consider only the listed NGK Iridium IX 3.5L option; the 3.6L listings are not interchangeable by assumption.
