The most common oil filter for a 2008 Honda Civic with the 1.8L engine is Honda Genuine part number 15400-PLM-A01. If your Civic uses the 2.0L engine found in the Si, a different filter applies. Always verify with your VIN or the owner's manual to be certain.
In more detail, the 2008 Civic line-up includes two main engine families: the 1.8L i-VTEC (R18A1) used in most trims (DX/LX/EX/EX-L) and the 2.0L engine used in the Civic Si. The oil filter is not universal across these engines; the correct part number depends on the exact engine and configuration. To be sure, consult the owner's manual, use a VIN-based parts lookup from Honda or a trusted parts retailer, or ask a mechanic to confirm the correct filter for your specific car.
Engine options and how they affect filter choice
The 2008 Civic offered two primary engines, which influences which filter you should buy. The guidance below helps you identify which path to follow.
- 1.8L i-VTEC (R18A1) — This is the standard engine for most 2008 Civics (DX, LX, EX, EX-L). The recommended OEM filter for this engine is typically Honda Genuine 15400-PLM-A01.
- 2.0L engine (Si) — The Civic Si uses a different 2.0L family of engines (K-series). This configuration requires the filter designed for that engine family.
After reviewing the engine, you can proceed to obtain the exact part number by using VIN-based lookup or checking the service manual. This ensures compatibility with your specific build and regional availability.
Where to buy and aftermarket options
If you prefer aftermarket solutions or need a readily available replacement, several reputable brands offer filters that cross-reference to Honda’s specifications. Check compatibility with your exact engine code and year before purchase.
- Honda Genuine (OEM) filters — the most reliable fit and designed for your exact engine.
- Bosch Premium FILTECH filters
- Mann-Filter
- Purolator
- Wix
When choosing aftermarket options, make sure to confirm that the filter is explicitly listed as compatible with the 2008 Civic’s engine variant (1.8L R18A1 or 2.0L Si/K-series). If in doubt, bring your VIN to the parts counter or use an online cross-reference tool to verify compatibility.
Tips for a correct install and maintenance
- Always use a new gasket for the oil drain plug and a fresh oil drain seal if your filter kit includes one.
- Check the filter’s thread size and O-ring diameter to ensure a proper seal and easy removal during the next change.
- Follow the manufacturer’s recommended oil type and capacity for your specific engine variant when performing oil changes.
- Dispose of used oil and the old filter according to local regulations.
By confirming your engine variant and using the correct filter, you’ll help maintain proper oil flow and engine protection for your 2008 Civic.
Summary
For most 2008 Honda Civics with the 1.8L engine, the standard choice is the Honda Genuine oil filter 15400-PLM-A01, but Si models with the 2.0L engine require a different filter tailored to that engine. Always verify the exact part number through VIN-based lookup, the owner's manual, or a trusted parts retailer. If you prefer aftermarket options, brands like Bosch, Mann-Filter, Purolator, Wix, and others offer compatible filters—just confirm compatibility with your engine variant before purchasing.
