The correct oil filter part number depends on which engine your 2009 Accord uses. The most common OEM numbers are 15400-RAA-A01 for the 2.4-liter four-cylinder engine and 15400-5G2-A01 for the 3.5-liter V6 engine. Verify with your vehicle’s engine code or the filter itself before ordering.
In that model year, the Accord was offered with two engines: a 2.4L inline-four (K-series) and a 3.5L V6 (J-series). Each uses a different spin-on oil filter design, so the part numbers differ accordingly. If you aren’t sure which engine your car has, you can check the VIN, under-hood stamping, or the owner’s manual to confirm the engine type and then choose the matching filter.
Engine-specific oil filter numbers
Use the engine type to determine the correct part number. The two primary configurations in the US market are listed below.
- 2.4L I4 (K-series) engine — Honda OEM oil filter: 15400-RAA-A01
- 3.5L V6 (J-series) engine — Honda OEM oil filter: 15400-5G2-A01
Note: Aftermarket filters that claim compatibility with Honda two-digit models may also fit; always confirm the exact fit for your engine variant, year, and market. The filter should match thread size and sealing groove; incorrect filters can lead to leaks or poor oil circulation.
How to identify your engine type
To confirm the correct filter number, locate your engine code—K-series for 2.4L, J-series for 3.5L—or use the vehicle identification number (VIN) to pull the exact powertrain. The engine code is typically stamped on the engine block near the exhaust header or on a label under the hood.
Where to find the part in catalogs
When shopping, use the OEM part numbers above or search by engine code and model year in Honda parts catalogs or reputable aftermarket retailers. Enter the VIN if available to ensure the precise match.
Summary
For a 2009 Honda Accord, the oil filter number differs by engine: 15400-RAA-A01 for the 2.4L I4 and 15400-5G2-A01 for the 3.5L V6. Always verify with the engine code or VIN before purchase, and consult the filter canister or owner’s manual if in doubt.
