The 2021 Honda Civic uses two air filters: an engine air filter and a cabin air filter. The exact part numbers depend on market and engine trim, so you should verify with your VIN. Commonly cited numbers are engine filter 17220-RNA-A00 (with updates such as -A01) and cabin filter 80292-S5A-000 (with variations like -003 in some markets).
Engine air filter
The engine air filter sits in the air intake housing and protects the engine from dust and debris. For the 2021 Civic, Honda’s catalog shows a couple of common part numbers depending on production run and region. To ensure you get the right one for your car, always confirm via VIN or official parts lookup.

Part numbers can shift with revisions or regional differences, so double-check with your vehicle’s VIN before purchasing.
Cabin air filter
The cabin air filter cleans the air entering the interior through the HVAC system. Like the engine filter, cabin filter part numbers can vary by market and trim level, so it’s important to confirm the correct PN for your specific Civic.

How to verify and order the right part
To avoid buying the wrong filter, use a precise lookup that ties the part number to your VIN and market. This ensures the filter fits your engine and HVAC system correctly.
- Check the owner's manual or maintenance booklet for the recommended filter part numbers for your exact model and year.
- Use your VIN on Honda’s official parts site or through a Honda dealer portal to fetch the exact engine and cabin filter PN.
- If shopping at an auto parts retailer, enter your year, make, model, engine type, and market, then cross-check the results against your VIN.
Verifying with VIN helps prevent mismatches and ensures optimal performance and filtration.
