For most 2012 Civics with the 1.8-liter engine, the OEM oil filter is Honda part number 15400-PLM-A02. If you have a Civic Si with the 2.4-liter engine, the filter is different, so you should verify the exact part number using your VIN or owner's manual.
Engine options in the 2012 Civic
How to tell which engine you have
The 2012 Honda Civic was offered with two primary gasoline engine options in the U.S.: the 1.8-liter i-VTEC for the standard LX/EX trims and a 2.4-liter engine for the Civic Si. The oil filter part number varies by engine, so identifying your engine code or trim helps ensure you buy the correct replacement.
Before listing the recommended filter choices, note that part numbers can vary by market and production run.
- 1.8L i‑VTEC engine (LX/EX/EX-L): Honda OEM oil filter part number 15400-PLM-A02. This is the most common filter for 2012 Civics in North America.
- 2.4L engine used in the Civic Si: This model uses a different oil filter than the 1.8L. Check your owner's manual or confirm with a Honda dealer or parts retailer using your VIN to obtain the correct part number.
The two items above illustrate the general guidance: the 1.8L uses 15400-PLM-A02, while the 2.4L Si requires a different part number that must be verified for your specific vehicle.
How to verify the correct filter for your car
To avoid buying the wrong filter, identify your engine code and cross-check with the vehicle's VIN or the official parts catalog. You can also consult the owner's manual or ask a Honda dealer to confirm the exact replacement part number for your specific vehicle.
- Check the owner's manual for the recommended oil filter part number and oil grade for your trim level.
- If you have the 1.8L engine, you are likely to use 15400-PLM-A02; if you have the 2.4L Si engine, obtain the alternative part from Honda or a verified parts database using your VIN.
- When purchasing aftermarket filters, ensure the filter matches the 65–67 mm cartridge size and the correct thread size for your engine, and that it is rated for your oil capacity and type.
Note: Not all aftermarket filters are interchangeable between engines. Using the wrong filter can cause leaks or inadequate filtration, so confirm before purchase.
Summary
For a 2012 Honda Civic, the most common oil filter is Honda part 15400-PLM-A02 for the 1.8L engine. If your car is a Civic Si with the 2.4L engine, use the filter specified for that engine by Honda; always verify with your VIN/engine code. When in doubt, consulting a dealer or a trusted parts retailer ensures you get the correct replacement.
