The 2021 Honda CR‑V offered two main powertrains in the United States: a 1.5-liter turbocharged gas engine and a hybrid system. Each engine uses a different oil filter, and part numbers can vary by market and revision. This article clarifies the two most common OEM numbers and how to confirm your exact fit.
Engine variants and corresponding oil filters
To help you quickly identify the correct filter, note the two primary engine options for the 2021 CR‑V and their respective OEM part numbers.
- 1.5L turbocharged engine (L15B7) — Honda OEM oil filter part number: 15410-5A2-A01. Verify with your vehicle's VIN.
- 2.0L hybrid engine — Honda OEM oil filter part number: 15410-5A2-821. Verify with your vehicle's VIN.
These part numbers correspond to the typical Honda Parts catalogs used in the United States and may vary in other regions. Always cross-check with official sources.
How to confirm the exact part number for your CR‑V
Because small revisions or regional catalogs can introduce changes, use these steps to confirm the right oil filter for your specific SUV:
- Gather your VIN from the lower dashboard or door jamb.
- Visit the official Honda Parts website or contact a Honda dealer with your VIN to pull the exact oil filter part number.
- Check the owner's manual or maintenance schedule, which sometimes lists the filter part number for your engine code.
Using the wrong filter can affect performance and engine safety, so verification is essential.
Additional considerations
Other factors that may influence the correct part include regional product revisions, aftermarket vs OEM options, and whether your CR‑V uses the standard or a special maintenance kit. When in doubt, opt for an OEM filter and replace the gasket as recommended in the service manual.

The two common OEM numbers are 15410-5A2-A01 for the 1.5L turbo and 15410-5A2-821 for the 2.0L hybrid, but always confirm with your VIN and local dealer catalogs, as part numbers can vary by market and revision.
