Best Spark Plugs For Honda Accord: Compare 10 Fitment Options

#1 · Best Overall

1. NGK Laser Iridium

Best for: 2013–2017 2.4L Accord.

Why it ranks #1: Specifically listed for 2013–2017 Accord 2.4L L4 models; the four-plug set also includes original packaging and hardware.

This four-pack of genuine NGK Laser Iridium plugs is listed specifically for 2013–2017 Honda Accord 2.4L L4 models, narrowing its stated application to that engine and year range. The listing calls the parts direct replacements and includes original packaging and hardware.

The specified 2.4L L4 application and 2013–2017 model-year span give owners a clear vehicle range to check before a replacement job. NGK Laser Iridium is the named plug type, and the genuine-parts description identifies the brand and construction category. Four plugs come in the set, with original hardware included; the direct-replacement description supports routine service. Unlike broader L4 listings, this product’s supplied Accord fitment names the 2.4L engine rather than 2.0L models.

Skip it if you own a 2013–2017 2.0L Accord; Sixity Auto’s B0D1S7BQNZ lists both 2.0L and 2.4L L4 applications.

This set suits owners replacing plugs in a listed 2013–2017 Accord 2.4L L4 who want NGK Laser Iridium parts and included hardware. Its stated engine application does not include the 2.0L.

#2 · Best 2013–2017 L4 Coverage

2. NGK Iridium IX 2013–2017

Best for: 2013–2017 four-cylinder owners.

Why it ranks #2: The four-plug set explicitly covers 2013–2017 Accord 2.0L and 2.4L L4 engines, making its stated application broader than the 2.4L-only listing.

A genuine NGK Iridium IX four-pack covers listed 2013–2017 Accord 2.0L and 2.4L L4 applications, giving owners of those engines a specific replacement option. The package includes original hardware, while the listing identifies the plugs as direct replacement auto parts for the stated fitment range.

The four-plug pack matches the listed four-cylinder Accord applications, so it supplies a set sized to the product’s stated 2.0L and 2.4L L4 coverage. Genuine NGK Iridium IX construction identifies the plug type, and included original packaging and hardware keep the supplied parts together for a replacement job. The direct-replacement description points to routine plug service rather than an accessory upgrade; the stated Accord coverage is limited to model years 2013–2017.

Skip it if you own a 3.5L V6 Accord; Sixity Auto’s B0D15NQ5T6 listing covers the 2008–2017 V6 instead.

This pack suits owners servicing a listed 2013–2017 Accord 2.0L or 2.4L L4 who want NGK Iridium IX plugs and included hardware. Its stated fitment does not cover the V6 or older four-cylinder years.

#3 · Best V6 Fit

3. NGK Iridium IX V6

Best for: Accord V6 tune-up pack.

Why it ranks #3: This six-plug set specifically fits Accord 3.5L V6 models from 2008–2017 and includes original packaging and hardware.

Six genuine NGK Iridium IX plugs match the listing’s 3.5L V6 Accord coverage from 2008 through 2017, making this a one-pack replacement set for that engine. Original packaging and hardware are included, and the seller describes the plugs as direct replacement auto parts.

The six-piece count pairs with the listed 3.5L V6 application, providing a full pack for the Accord engine configuration identified here. Its model-year range spans 2008–2017, useful for owners checking an older or newer Accord within that range. NGK Iridium IX is the named plug type, while the included hardware and direct-replacement description support a standard replacement workflow. This listing does not state coverage for four-cylinder Accord engines.

Skip it if you have a four-cylinder 2013–2017 Accord; Sixity Auto’s B0D1S7BQNZ lists 2.0L and 2.4L L4 fitment.

Choose this set for a listed 2008–2017 Accord 3.5L V6 replacement using NGK Iridium IX plugs. Its six-plug pack and stated fitment target the V6, so it is not the listed choice for four-cylinder Accords.

#4

4. A-Premium Iridium Platinum

• Core Material: Platinum
• Top Material Type: Iridium
• Gap Size: 0.04 in

Best for: Earlier 2.4L Accord service.

Why it ranks #4: The listing names Accord 2008–2012 2.4L L4 without PZEV and provides a 0.044-inch stated gap.

A four-pack of fine-wire iridium-platinum plugs lists Accord 2.4L L4 fitment for 2008–2012, giving owners in that range a targeted replacement set. The listing also specifies a 0.044-inch gap and identifies Acura and other Honda applications, although Accord fitment excludes PZEV vehicles.

The four-piece pack is listed for 2008–2012 Accord 2.4L L4 models without PZEV, a useful boundary to check before starting a replacement. Its fine-wire iridium-platinum construction names the electrode materials, while the stated 0.044-inch gap gives a concrete specification for service planning. The broader listed applications include certain CR-V, Crosstour, Civic, ILX, and TSX models, but that wider coverage does not remove the Accord PZEV exclusion.

Skip it if you have a PZEV Accord; the listing excludes it, while Sixity Auto’s B0D1S7BQNZ covers specified 2013–2017 L4 applications.

This set suits owners of a non-PZEV 2008–2012 Accord 2.4L L4 who want the listed fine-wire iridium-platinum plugs. Its stated Accord compatibility excludes PZEV models, an important boundary before purchase.

#5 · Best Older Accord Iridium

5. NGK Iridium IX 1990–2002

• Core Material: Iridium
• Top Material Type: Iridium
• Gap Size: 0.04 in

Best for: Older Accord Iridium IX set.

Why it ranks #5: This four-plug set explicitly fits 1990–2002 Accord 2.2L and 2.3L L4 models and identifies iridium as its core material.

A four-pack of genuine NGK Iridium IX plugs lists 1990–2002 Accord 2.2L and 2.3L L4 fitment, giving owners of those older engines an iridium replacement option. The product includes original packaging and hardware and is described as a direct replacement.

The stated 1990–2002 coverage identifies the older Accord generations this pack targets, while the 2.2L and 2.3L L4 specifications narrow the application further. Iridium IX is the named plug type, and the four-piece quantity supplies a set for the listed four-cylinder application. Included hardware and the direct-replacement description support a conventional service workflow. The supplied Accord fitment does not extend beyond 2002, so newer owners need another application.

Skip it if you prefer the listed copper-core option for these older Accords; Sixity Auto’s B01N25WJEL covers 1990–2002 2.2L and 2.3L L4 models.

This set fits owners seeking NGK Iridium IX plugs for a listed 1990–2002 Accord 2.2L or 2.3L L4 service. Its stated compatibility ends in 2002, so check another application for newer Accords.

6. NGK V-Power

• Core Material: Copper
• Top Material Type: Ceramic, Metal
• Gap Size: 0.04 in

Best for: Older Accord copper replacement.

Why it ranks #6: The listing covers 1990–2002 Accord 2.2L and 2.3L L4 applications; its copper core is described as an economical performance option for older vehicles.

NGK’s V-groove electrode design and precision laser-welded construction identify this four-pack for older Accord owners seeking the listed copper-core plug. Sixity Auto specifies fitment for 2.2L and 2.3L L4 Accords from 1990–2002, with nickel electrodes for spark development.

The copper core and nickel electrode make this a distinct option from the listed iridium products, while the V-groove design is described as supporting spark development. Precision laser-welded electrode construction adds a named manufacturing detail. The four-pack is specified for 2.2L and 2.3L Accord L4 engines from 1990–2002, helping owners match the intended older applications. Its listing describes it as an economical performance plug for older vehicles, not as a fit for newer Accords.

Skip it if you want an iridium plug for a 1990–2002 Accord; Sixity Auto’s B09B3LLJWX lists Iridium IX coverage for those engines.

Choose this set for a listed 1990–2002 Accord 2.2L or 2.3L L4 when the copper-core V-Power design matches your service plan. Its fitment does not extend to later Accord years.

7. A-NAFTULY 6994 Iridium

• Core Material: Iridium
• Top Material Type: Iridium
• Gap Size: 0.04 in

Best for: 2003–2007 Accord 2.4L.

Why it ranks #7: Its stated fitment includes 2003–2007 Accord 2.4L L4 and the four-pack provides four iridium plugs, though the brand differs from the NGK listings.

This four-pack lists iridium plug fitment for 2003–2007 Honda Accord 2.4L L4 models, providing an application-specific option for those earlier four-cylinder cars. A-NAFTULY also lists several other Honda and Acura applications and gives a 0.04-inch gap specification.

The listed Accord range is specific to 2.4L L4 models from 2003 through 2007, helping buyers separate this set from plugs listed for later Accords. Four plugs are included, and the stated 0.04-inch gap provides a service specification to check against the vehicle’s requirements. The product also lists compatible CR-V, Element, Civic, TSX, and RSX applications, but those broader applications do not expand its stated Accord years.

Skip it if you have a 2008–2012 Accord 2.4L; A-Premium’s B0CD2FGLQP lists that range, excluding PZEV vehicles.

This A-NAFTULY set suits owners servicing a listed 2003–2007 Accord 2.4L L4 and seeking a four-plug iridium pack. Its Accord coverage stops at 2007, so it does not match later model years.

Listed on Amazon as: Iridium Spark Plugs 4 Pack 6994 IZFR6K11 Compatible with 2003-2007 Honda Accord 2.4 CRV Element & Acura TSX 2003 2004 2005 2006 2007 2008, Civic & RSX 2.0L 02-05 Replaces IZFR6K-11, 9807B-561BW

#8

8. NGK LKAR7BIX-11S

• Core Material: Iridium
• Top Material Type: Metal
• Gap Size: 0.6 millimeters

Best for: Performance-focused Iridium IX.

Why it ranks #8: This NGK Iridium IX four-pack has a 0.6-millimeter gap and fine iridium tip, but the supplied listing does not specify Accord fitment.

NGK’s 0.6-millimeter laser-welded fine iridium tip is paired with a tapered ground electrode, features the listing connects to a stable spark and reduced electrical quenching. This four-pack targets performance enthusiasts, but the supplied product information does not identify Honda Accord fitment or model years.

The fine iridium tip is specified as laser welded and intended for high durability and a consistently stable spark, while the tapered ground electrode minimizes electrical quenching. A longer insulator nose is listed to help prevent fouling, and corrugated insulator ribs are described as preventing flashover. The triple gasket seal is intended to eliminate combustion gas leakage. These construction details inform a performance-oriented choice, but the listing’s M12 x 1.25 thread and plug features do not establish Accord fitment.

Skip it if you need a plug with listed Accord fitment; Sixity Auto’s B0D1S7BQNZ specifies 2013–2017 2.0L and 2.4L L4 models.

This four-pack is aimed at performance-oriented buyers interested in NGK Iridium IX electrode and sealing features. For an Accord replacement, establish vehicle compatibility first: the supplied listing names no Accord engine or model-year range.

#9

9. NGK LKR7DIX-11S

• Core Material: Iridium
• Top Material Type: Metal
• Gap Size: 0.04 in

Best for: Iridium IX spark stability.

Why it ranks #9: The four-pack lists iridium construction and a 0.04-inch gap, but supplied vehicle compatibility does not identify a Honda Accord application.

NGK pairs a 0.6-millimeter laser-welded fine iridium tip with a tapered ground electrode in this four-pack, linking its construction to stable sparking and reduced electrical quenching. The listing emphasizes performance, but does not give a Honda Accord application or model-year range.

The fine iridium tip is described as durable and intended to deliver a consistently stable spark, while the tapered ground electrode minimizes electrical quenching. NGK also lists corrugated insulator ribs to prevent flashover and a triple gasket seal to eliminate combustion gas leakage. Together these details help buyers assess the plug’s construction and sealing features before a service job. The supplied listing specifies a 0.04-inch gap but does not establish fitment for a particular Accord.

Skip it if you want an Accord-specific application listed; Sixity Auto’s B0CZSLNSPB specifies 2013–2017 2.4L L4 fitment.

Consider this NGK Iridium IX four-pack if its stated plug specifications suit your service needs and vehicle. The supplied facts do not name Accord compatibility, so confirm the application through an appropriate fitment source before installation.

#10

10. Bosch 9614 Double Iridium

• Core Material: Iridium
• Top Material Type: Iridium

Best for: Fine-wire iridium technology.

Why it ranks #10: The Bosch listing describes double-iridium construction but supplies no Accord-specific fitment, making it the least supported match for this vehicle search.

Bosch’s double-iridium design places iridium at both the firing pin and ground electrode, a specific construction intended to combine ignitability and durability. The four-pack uses a 360-degree laser-welded ultra-fine firing pin; the supplied listing does not name a Honda Accord model-year or engine fitment.

The double-iridium electrodes and ultra-fine firing pin distinguish this plug’s construction, and Bosch says the design can reduce voltage requirements by up to 24% compared with standard copper plugs. A tapered ground electrode is also described in the supplied product details as part of its performance design. Nickel-plated rolled threads are specified for corrosion resistance and plug removal, while the four-pack suits a set-based replacement workflow. Accord-specific fitment is not provided.

Skip it if you need stated Accord compatibility; Sixity Auto’s B0D1S7BQNZ lists 2013–2017 2.0L and 2.4L L4 coverage.

This four-pack fits buyers prioritizing Bosch double-iridium construction, fine-wire design, and corrosion-resistant threads. Consider it only when its vehicle fitment is established for your Accord; the supplied listing gives no Accord engine or year range.
