There isn’t a single universal spark plug part number for the 2015 Accord. The correct plug depends on which engine the car uses (2.4-liter inline-4 or 3.5-liter V6) and the market where the car was sold. To get the exact OEM part number, you’ll need the vehicle’s engine code or VIN and then check Honda’s official parts catalog or contact a dealer.
Engine options in the 2015 Accord
The 2015 Honda Accord offered two gasoline engines, each with its own spark plug specification. This distinction matters because plug type, heat range, and gap vary by engine.
2.4-liter inline-4 (K-series)
- The 2.4L four-cylinder engine variant used in many LX, EX, and Touring trims requires spark plugs matched to that cylinder head and ignition system.
Engine-specific plugs are required to ensure proper combustion and reliability; always verify the exact part using official sources for your VIN.
3.5-liter V6
- The 3.5L V6 variant used in higher trims like EX-L and Touring uses a different spark plug specification than the 2.4L engine.
Because the V6 has its own heat-range and thread specifications, the correct plug must be confirmed for your vehicle’s exact configuration.
Finding the exact spark plug part number for your car
To identify the correct plug for your specific car, follow these steps. They help ensure you obtain the precise OEM part number or a suitable equivalent.
- Locate your VIN and engine code. The VIN is usually found on the driver’s door jamb sticker and registration; the engine code is listed in the service manual or under the hood’s information placard.
- Check the owner's manual or service manual for the recommended spark plug type and gap for your engine variant.
- Use Honda’s official Parts Catalog or contact a Honda dealer with your VIN to retrieve the exact OEM spark plug number.
- If you use cross-reference sources (NGK, Denso, etc.), verify cross-compatibility with your engine’s heat range, thread size, and reach before purchasing.
- Confirm the recommended gap specification before installation (the gap is typically around 0.043 inches for many Honda engines, but always verify in the manual).
- Replace all spark plugs if you’re performing a full tune-up to maintain even performance across cylinders.
These steps ensure you install the precise plug your engine requires, whether you choose OEM or a reputable aftermarket equivalent.
Notes and practical tips
Regional differences and dealer-approved part catalogs can affect the exact part number. If you’re unsure, rely on the dealer or a trusted parts retailer with your VIN. Providing the engine code or VIN helps the parts lookup return the correct plug and cross-reference options.
Summary
The 2015 Honda Accord does not have a single spark plug part number. The correct plug depends on whether your car has the 2.4L inline-4 or the 3.5L V6 engine, and it may vary by market. To obtain the exact OEM part number, check the VIN with Honda’s parts catalog or your local dealer, and confirm the recommended heat range and gap before purchase. When in doubt, use an OEM or well-reviewed aftermarket plug that matches the engine’s specifications and replace all plugs in a set for optimal performance.

What kills spark plugs quickly?
Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn't functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug's electrode wearing out faster.
