There isn’t a single universal STP oil filter number for all 2008 Civics; the correct STP part depends on the engine variant (for example, the 1.8L I4 versus the 2.0L Si engine). Identifying the exact engine code is the surest way to confirm the right STP filter.
Understanding the 2008 Honda Civic engine options
The 2008 Honda Civic came in several trims with at least two main engine setups. Most LX, EX, and EX-L models used a 1.8-liter I4 engine (commonly referred to as the R18A1 family), while the Civic Si used a 2.0-liter I4 (K20Z3). Because the filter size and threading can vary by engine, the STP part number is not interchangeable across these variants.
How to identify the correct STP oil filter
To ensure you purchase the correct STP filter for your Civic, follow these steps.
Before the list, here is an approach you can take to verify the right part:
- Find your engine code and trim level — for most 2008 Civics, the 1.8L model uses the R18A1 family while the Si uses the K20Z3 family.
- Check STP’s official product catalog or website for a cross-reference by engine code and model year, then confirm the exact part number for your Civic configuration.
- If you’re shopping in-store or online, use your VIN or describe the engine type to the parts advisor to get the correct STP filter match.
- When in doubt, cross-check the filter’s physical characteristics (thread size, gasket diameter, and overall dimensions) against the filter currently installed on your vehicle.
Using these steps helps prevent selecting an STP filter that doesn’t fit or function correctly in your specific Civic.
In summary, the right STP oil filter number for a 2008 Honda Civic depends on whether your car has the 1.8L engine (R18A1) or the 2.0L Si engine (K20Z3). The most reliable path is to identify the engine code and consult STP’s cross-reference catalog or contact a parts professional with your VIN.
