For the 2018 Honda Fit, the engine air filter is commonly listed as 17220-RNA-003 and the cabin air filter as 80292-S5A-000 in many markets. Exact numbers can vary by market or production run, so verify with your VIN before ordering.
What the numbers refer to and how they can vary
The Honda Fit uses two separate filters that serve different purposes: an engine air filter and a cabin air filter. The specific part numbers can differ depending on the country, trim level, and manufacturing date. This article outlines the two filters and how to confirm the precise numbers for your vehicle.
Engine air filter
The engine air filter cleans air before it enters the engine. In North American 2018 Fit models, the OEM engine air filter part number is commonly cited as 17220-RNA-003, though regional variations may apply. Always verify with your vehicle’s VIN and the official parts catalog to ensure the exact match.
Before ordering, consider these points about engine air filters:
- Common engine air filter part number for many markets: 17220-RNA-003
- Regional or production variations can occur; confirm with official catalogs
- OEM parts are preferred to ensure proper fit and performance
Concluding note: the engine air filter part number is specific to your region and production batch, so checking the VIN against Honda’s catalog is the safest step.
Cabin air filter
The cabin air filter cleans air entering the vehicle’s interior through the HVAC system. For many markets, the OEM cabin filter part number cited for the 2018 Fit is 80292-S5A-000, but regional variants may exist. Verify with the VIN and local catalogs to confirm the exact part.
Before ordering a cabin filter, consider:
- Common cabin filter part number for many markets: 80292-S5A-000
- Regional variants may apply; check the official catalog for your VIN
- Choosing an OEM filter helps maintain filtration efficiency and fit
Concluding note: cabin filter numbers vary by market and production run; always confirm with a trusted parts source using your VIN.
How to verify the correct part numbers for your car
To ensure you purchase the right filters, use these verification methods:
- Access Honda's official parts catalog and enter your vehicle’s VIN or exact model details to pull the precise part numbers.
- Consult your owner's manual or maintenance guide, which may list the recommended filter part numbers for your region.
- Contact a Honda dealership or authorized parts retailer with your VIN to confirm the exact OEM numbers.
Once you have the precise part numbers, compare them with dimensions and filter type (engine vs. cabin) to guarantee compatibility. If you replace both filters, you might opt for a complete OEM replacement kit for convenience.
Why using the correct part matters
Using the wrong filter can affect engine performance, fuel efficiency, and interior air quality. OEM parts are designed to fit precisely and meet the car’s filtration specifications. Mismatched filters may cause leaks or reduced filtration effectiveness.
Summary
The 2018 Honda Fit relies on two filters: an engine air filter (commonly 17220-RNA-003 in many markets) and a cabin air filter (commonly 80292-S5A-000). Because part numbers can vary by country, market, and production run, always verify with your VIN via Honda’s official catalogs or a trusted parts retailer before purchasing.
