Best Spark Plugs For Honda Accord: Compare 10 Options
A strong Honda Accord spark plug choice matches the car’s exact engine and year, with an electrode material and pack size suited to the application. The Sixity NGK Iridium IX 4-Cylinder is a clear starting point for listed 2.0L and 2.4L four-cylinder Accords, while a separate six-pack is listed for 3.5L V6 models. This roundup includes direct-fit options for several Accord engine ranges, plus plugs whose supplied information does not establish Accord fitment.
That distinction matters: a familiar brand or matching thread description alone does not confirm compatibility. Check your owner’s manual or the vehicle fitment tool before ordering, and compare engine, model year, plug count, and specified gap against the listing.
The Sixity NGK Iridium IX 4-Cylinder leads for listed 2.0L and 2.4L Honda Accord four-cylinder applications because the product title and fitment details name those engines and a defined Accord range. It is a four-pack of genuine NGK Iridium IX plugs, making it the most straightforward match among these options for those listed configurations. For an Accord with a 3.5L V6, choose the separately listed Sixity NGK Iridium IX V6 instead, and confirm the exact vehicle fitment before purchase.

Detailed Reviews: Best Spark Plugs For Honda Accord
Why it ranks #1: Its listed fitment covers Accord 2.0L and 2.4L L4 applications, and the four-pack contains genuine NGK Iridium IX plugs.
Genuine NGK Iridium IX plugs arrive as a four-piece set for listed 2013–2017 Accord 2.0L and 2.4L L4 applications. That vehicle- and engine-specific coverage gives owners of those models a direct-replacement option, with the included hardware and original packaging supporting a straightforward replacement-parts workflow.
The listing identifies Accord model years 2013 through 2017 and both 2.0L and 2.4L L4 engines, making the application range easy to compare with the vehicle before ordering. Four plugs are supplied as a set, while the direct-replacement description positions them for routine plug replacement rather than a modification. Genuine NGK parts and included hardware provide a defined parts package; use the listing’s fitment check to ensure the specific vehicle matches the stated year, engine, and cylinder layout.

NGK V-Power plugs are listed for 1990–2002 Accord 2.2L and 2.3L L4 engines, pairing an older-vehicle application with a copper-core design. The four-pack’s laser-welded electrode and V-groove construction support spark development, making it a targeted option for those specified Accord generations.
The product names two Accord engine sizes, 2.2L and 2.3L L4, across model years 1990–2002, which helps owners of older vehicles narrow their selection. Its copper core and nickel electrode define the materials, while the precision laser-welded construction and advanced V-groove design are specified to enhance spark development. The four-plug quantity suits the listed four-cylinder applications. NGK describes it as an economical performance plug for older vehicles, rather than an iridium product.

#4 · Twin-Tip Design
4. Sixity DENSO Iridium TT
- Core Material: Iridium
- Compatible with Vehicle Type: Car, Truck
- Gap Size: 0.04 millimeters
Best for: 1996–2007 Accord Twin-Tip.
Why it ranks #4: The listing covers Accord 2.2L and 2.4L L4 applications and describes a twin-tip design with iridium and platinum electrodes.
DENSO Iridium TT plugs pair a 0.4-millimeter iridium center electrode with a 0.7-millimeter platinum ground electrode, bringing twin-tip construction to this four-pack. Sixity Auto lists Accord 2.2L and 2.4L L4 applications from 1996 through 2007, giving owners a defined older-model range.
The listing specifies a 0.4 mm iridium center tip and 0.7 mm platinum ground tip, so the twin-tip design is backed by named electrode materials and dimensions. Sixity Auto lists Honda Accord 2.2L and 2.4L L4 models from 1996–2007, while the four-plug pack suits the stated four-cylinder layout. The product description associates a larger spark with more power and fuel economy; those are stated benefits, not a guarantee for every vehicle or operating condition.
- Listed for 1996–2007 Accord 2.2L L4
- Listed for 1996–2007 Accord 2.4L L4
- 0.4 mm iridium center electrode
- 0.7 mm platinum ground electrode

Consider this DENSO four-pack for a listed 1996–2007 Accord 2.2L or 2.4L L4 when twin-tip electrode construction is appealing. Its supplied Accord coverage stops at 2007 and does not name V6 models.

5. A-Premium Iridium Platinum
- Core Material: Platinum
- Compatible with Vehicle Type: Honda CR-V, Honda Accord, Honda Crosstour…
- Gap Size: 0.04 in
Best for: Older 2.4L Accord Applications.
Why it ranks #5: Its fitment details list Accord 2.4L L4 applications, and the four-pack is specified with an iridium top and platinum core.
A-Premium lists this four-pack for 2008–2012 Accord 2.4L L4 models without PZEV (Fed Emissions), giving that specific group a defined application. Its iridium-topped platinum-core specification and 0.044-inch gap provide concrete details for buyers comparing replacement plugs for the stated vehicles.
The fitment list names Accord 2008–2012 2.4L L4 without PZEV (Fed Emissions), alongside other Honda and Acura applications; this emissions qualification is important when narrowing the application. The set contains four plugs, and the listed gap is 0.044 inch, giving buyers another specification to check against their vehicle’s requirements. Platinum is identified as the core material and iridium as the top material. These details make the product a targeted option, not a universal Accord fit.
- Listed for 2008–2012 Accord 2.4L L4 without PZEV
- Four-plug pack
- Platinum core material with iridium top material
- 0.044-inch listed gap
- Accord fitment excludes the listed PZEV (Fed Emissions) configuration.

6. A-NAFTULY 6994 Iridium
- Core Material: Iridium
- Compatible with Vehicle Type: Car
- Gap Size: 0.04 in
Best for: 2003–2007 Accord 2.4L.
Why it ranks #6: The four-pack lists Accord 2.4L L4 fitment and an iridium core, though the supplied fitment range is narrower than the higher-ranked options.
This four-pack lists Honda Accord 2.4L L4 applications from 2003 through 2007, alongside several other Honda and Acura models. Its iridium construction and stated 0.04-inch gap give buyers concrete specifications, while the named year and engine range help narrow the intended Accord application.
The Accord fitment is specifically identified as 2.4L L4 for model years 2003–2007, making the application clearer than a general vehicle-type label. The four-plug quantity provides a complete set for the listed four-cylinder application. Iridium is named as both core and top material, and the 14 mm thread and 0.04-inch gap add specifications for application comparison. The broader fitment list includes CR-V, Element, Civic, TSX, and RSX models, but does not broaden the stated Accord year range.
- Listed for 2003–2007 Accord 2.4L L4
- Four iridium spark plugs
- 14 mm thread specification
- 0.04-inch listed gap
- The Accord application is limited to the listed 2003–2007 2.4L L4.

7. NGK LKAR7BIX-11S Iridium IX
- Core Material: Iridium
- Compatible with Vehicle Type: Car, Truck
- Gap Size: 0.6 millimeters
Best for: Stable-Spark Iridium IX.
Why it ranks #7: This four-pack has a fine 0.6 millimeter iridium tip and listed gap, but the supplied details do not identify a Honda Accord application.
A 0.6-millimeter laser-welded fine-iridium tip is the defining feature of this NGK Iridium IX four-pack, supporting a consistently stable spark and high durability according to the listing. Its performance-focused design also specifies a tapered ground electrode to reduce electrical quenching, but no Accord application is provided.
NGK pairs the fine iridium tip with a tapered ground electrode, linking the electrode geometry to the stated stable spark and reduced electrical quenching. A longer insulator nose helps resist fouling, while corrugated insulator ribs are listed to prevent flashover; together these details address ignition reliability. The triple gasket seal is specified to eliminate combustion-gas leakage. The pack contains four plugs, but the supplied product information does not identify Accord years or engines, so the listed engineering details cannot establish fitment.
- 0.6 mm laser-welded fine-iridium tip
- Tapered ground electrode minimizes electrical quenching
- Longer insulator nose helps prevent fouling
- Triple gasket seal addresses combustion-gas leakage
- No Accord year or engine application is stated in the supplied details.
Skip it if you want a specifically listed Accord application; the Sixity Auto NGK Iridium IX set B0D1S7BQNZ names 2013–2017 L4 engines.
Consider this NGK set when its specified electrode, insulator, and sealing features suit the service need. For an Accord, the supplied details do not establish year or engine fit, so application remains a boundary.

8. NGK LKR7DIX-11S Iridium IX
- Core Material: Iridium
- Compatible with Vehicle Type: Car, Truck
- Gap Size: 0.04 in
Best for: Fine-Iridium Four-Plug Pack.
Why it ranks #8: The four-pack offers a 0.6 millimeter iridium tip, but its supplied compatibility information does not establish fitment for an Accord.
NGK’s 0.6-millimeter laser-welded fine-iridium tip is specified to provide high durability and a stable spark, making this four-pack a defined option for buyers focused on electrode construction. The listing also describes improved throttle response, but it does not identify a Honda Accord year or engine application.
The fine-iridium tip is paired with a tapered ground electrode that minimizes electrical quenching, connecting the listed materials and geometry to a stable spark. NGK also specifies a longer insulator and corrugated ribs to prevent flashover, while a triple gasket seal addresses combustion-gas leakage. Those features matter during operation, but do not determine vehicle compatibility. The package contains four plugs, and the listed 5/8-inch thread size and 0.04-inch gap provide additional specifications to compare against the required application.
- 0.6 mm laser-welded fine-iridium tip
- Tapered ground electrode minimizes electrical quenching
- Corrugated insulator ribs prevent flashover
- Triple gasket seal addresses combustion-gas leakage
- Accord year and engine fitment are not stated in the supplied details.
Skip it if you need a plug listing specific Accord applications; the Sixity Auto NGK set B0D15NQ5T6 names 2008–2017 3.5L V6 models.
This four-pack fits buyers prioritizing NGK’s stated fine-iridium, insulator, and sealing features. The supplied specifications do not establish Accord fitment, so it is not a confirmed choice for a particular year or engine.

9. Bosch 9614 Double Iridium
- Core Material: Iridium
- Compatible with Vehicle Type: Car
Best for: Double-Iridium Four-Pack.
Why it ranks #9: Bosch specifies double iridium electrodes and a four-pack, but the supplied product data does not list Accord-specific compatibility.
Bosch’s double-iridium construction places iridium at both the firing pin and ground electrode, a configuration Bosch says lasts four times longer than standard copper plugs. The four-pack suits buyers prioritizing that electrode design and long-life claim, though the supplied fitment details do not identify Accord years or engines.
A 360-degree laser-welded ultra-fine wire firing pin is specified to improve ignitability while reducing voltage requirements by up to 24%, connecting the electrode design to ignition-system demand. Nickel-plated rolled threads resist corrosion, which supports removal during later service. Bosch also describes these as OE technology, and four plugs arrive in the pack. The product information supplied here does not name a Honda Accord application, so the named construction benefits do not establish vehicle fitment by themselves.
- Iridium firing pin and ground-electrode inlay
- Bosch claims four times standard-copper life
- Laser-welded fine wire firing pin
- Nickel-plated rolled threads resist corrosion
- The supplied fitment details do not name Accord model years or engines.
Skip it if you need a listing that names your Accord engine and year; the Sixity Auto NGK set B0D1S7BQNZ lists specific 2013–2017 L4 applications.
Best suited to a buyer seeking Bosch double-iridium construction and the stated long-life and ignitability benefits in a four-pack. Treat Accord compatibility as unresolved from the supplied details, which name no Accord application.

10. Bosch 9619 Double Iridium
- Core Material: Iridium
- Compatible with Vehicle Type: Car
- Gap Size: 1.1 millimeters
Best for: Bosch Single Replacement Plug.
Why it ranks #10: Its double-iridium construction is specified, but this single plug has no listed Accord fitment and may not provide a complete set.
Bosch combines an iridium firing pin and ground-electrode inlay in this single OE-style plug, with a stated four-times-longer life versus standard copper plugs. Its 360-degree laser-welded fine-wire firing pin is specified to reduce voltage requirements by up to 24%, while the listing provides no Accord application.
The double-iridium electrode arrangement links both firing surfaces to Bosch’s stated longevity claim, while the laser-welded fine-wire design targets ignitability and lower voltage demand. Nickel-plated rolled threads resist corrosion and do not require anti-seize, which can simplify installation workflow. Unlike a multi-plug set, this listing is for one plug, making quantity an important service-planning consideration. The supplied fitment details give a 1.1-millimeter gap and M12 thread size but do not name an Accord year or engine.
- Iridium firing pin and ground-electrode inlay
- Bosch claims four times standard-copper life
- Laser-welded fine-wire firing pin
- Nickel-plated threads resist corrosion and need no anti-seize
- The listing is for one spark plug, not a multi-plug set.
Skip it if you need a four-plug set for a listed 2013–2017 L4 Accord; the Sixity Auto NGK set B0D1S7BQNZ covers those applications.
Choose this Bosch plug when a single replacement and its double-iridium, corrosion-resistant thread features match the service need. It is sold individually, and the supplied details do not specify Accord vehicle fitment.

View on AmazonWhy Accord fitment can be easy to misread
Accord fitment is easy to misread because the same model name covers different engines and plug applications. The supplied listings illustrate the trap: one NGK pack names 2.0L and 2.4L L4 engines, while another names a 3.5L V6 and contains six plugs. The V-Power listing identifies 2.2L and 2.3L L4 applications, and other direct-fit listings cover different engine combinations.
Do not treat a plug as compatible merely because it is an NGK or iridium product, or because a listing names a Honda. Confirm the exact engine, model year, and required part number using the vehicle’s manual or a fitment lookup.
Also check whether the listing’s pack quantity matches the number of plugs your engine requires; the supplied data does not establish a universal plug count for every Accord configuration.
What a gap specification does—and does not—tell you
A listed spark plug gap is useful for comparing products, but it does not prove that the plug is right for a particular Accord. The supplied specifications include values such as 0.04 inches, 0.044 inch, 0.6 millimeters, and 1.1 millimeters, with some entries using different units or describing a different measurement. For example, Bosch lists a 1.1 millimeter gap, while NGK lists a 0.6 millimeter gap on one Iridium IX model.
These figures should not be interpreted as interchangeable without checking the exact application and the manufacturer’s specification. A mismatch in plug type, reach, or gap can make an otherwise reputable plug unsuitable.
Use the vehicle-specific recommendation first, then verify the listing’s part number and dimensions. The provided data does not confirm whether any plug should be regapped before installation.
How to Choose Accord Spark Plugs
Engine and vehicle fitment
Look first for a listing that names your Accord’s engine, not merely the Honda brand. The products span 2.0L, 2.2L, 2.3L, 2.4L, and 3.5L applications, including four-cylinder and V6 engines. The Sixity NGK Iridium IX 4-Cylinder lists 2.0L and 2.4L L4 fitment, while the Sixity NGK Iridium IX V6 names the 3.5L V6.
The Sixity NGK V-Power names 2.2L and 2.3L L4 applications. Buyers with a clearly matching engine should favor those explicit fitment listings; if your engine or model year is not named, verify the part number before ordering rather than assuming a match.
Electrode material and design
Choose an electrode material and design that match the specified replacement plug for your engine. The list includes iridium-core options, a copper-core NGK V-Power, and the A-Premium plug with a platinum core and iridium top. Bosch describes double-iridium electrodes and claims up to four times the life of standard copper plugs, while DENSO describes a twin-tip design using iridium and platinum.
These product descriptions do not establish that one design suits every Accord. Buyers seeking a listed direct fit should prioritize the matching application over a material label; the material and design can then help distinguish options that are confirmed for the same engine.
Pack quantity and gap details
Check that the pack quantity and the listed gap suit the replacement job and your vehicle specification. Most options here are four-packs, while the Sixity NGK Iridium IX V6 is a six-pack and the Bosch 9619 Double Iridium is sold singly. Listed gap values vary, including 0.04 inches, 0.044 inch, 0.6 millimeters, and 1.1 millimeters.
Unit and product differences mean those numbers should not be compared without checking the vehicle’s prescribed specification. Buyers replacing a full set should favor a pack quantity that matches their engine’s required count; anyone buying a single plug should confirm whether a full set is needed.
Do not infer fitment from pack size or gap alone.
Which Spark Plugs Should I Choose for My Accord?
Choose the Sixity NGK Iridium IX 4-Cylinder if your Accord matches its listed 2.0L or 2.4L L4 fitment; it is the top-ranked, explicit match. For a listed 3.5L V6, the six-pack Sixity NGK Iridium IX V6 is the relevant pick. Owners of older 2.2L or 2.3L L4 applications can consider the Sixity NGK V-Power, while the Sixity DENSO Iridium TT covers listed 2.2L and 2.4L L4 applications.
For a listed 2.4L L4 application, compare the A-Premium Iridium Platinum and A-NAFTULY 6994 Iridium after checking their specific fitment details. The remaining options do not provide Accord-specific fitment in the supplied data, so verify compatibility before choosing them.
Frequently Asked Questions
How can I confirm the correct spark plug for my Accord’s engine and model year?
Check your owner’s manual or vehicle documentation for the engine and model year, then compare them with the plug’s listed fitment details. Match the engine configuration as well as the year range; if the listing does not clearly cover your Accord, verify compatibility before ordering rather than relying on the plug type alone.
Should I replace all spark plugs at once, and how many does my engine need?
Replacing the full set together is a practical approach, and the engine configuration determines how many plugs you need. The listed four-cylinder options are sold in four-packs, while the 3.5L V6 option is a six-pack. Confirm your exact engine and fitment before buying so the package count suits your vehicle.
What symptoms can indicate worn or incorrectly gapped spark plugs?
Misfiring, rough running, difficulty starting, or a noticeable loss of smooth performance can point to spark-plug trouble, though other issues can cause similar symptoms. Check the plugs and follow the vehicle’s service guidance; do not assume symptoms prove a gap problem, and confirm the required gap rather than guessing.
What should I do if a listing does not name my Accord’s engine?
Treat the fitment as unconfirmed and check the exact vehicle details before choosing that plug. Several options here do not provide Accord-specific fitment in the supplied information. Compare the listing with your vehicle documentation or confirm compatibility with the seller; a shared plug type or pack size is not enough to establish fit.
How should I choose between the listed 2.4L options?
Start by matching the listing’s fitment details to your exact Accord configuration. The supplied guidance identifies the Sixity NGK Iridium IX for listed 2.4L L4 applications, and also notes the A-Premium Iridium Platinum and A-NAFTULY 6994 Iridium as options to compare. Verify each product’s specific fitment before purchase.
Final Words
For a listed 2.0L or 2.4L L4 Accord, the Sixity NGK Iridium IX four-pack is the clearest choice in this roundup because its title and fitment details identify those applications. For a listed 3.5L V6, consider the separate six-pack. Older 2.2L or 2.3L L4 owners can compare the listed V-Power option.
In every case, confirm the exact vehicle fitment before ordering.
