The 2020 Acura ILX uses a standard Honda/Acura oil filter designed for the 2.4-liter i-VTEC engine, with the OEM part commonly cited as 15400-PLM-A02. Always verify the exact part for your vehicle using your VIN or the official manual, as regional variations can occur.
Overview of the ILX oil filter and oil specification
The ILX requires 0W-20 synthetic oil and employs a conventional canister-style oil filter that matches the 2.4L i-VTEC engine configuration. Using the correct filter helps ensure proper filtration, oil flow, and engine protection during service intervals. While the 2.4L engine is standard for the 2020 ILX, other trims or markets may have different engine specifications, which can affect filter compatibility.
OEM part number and regional compatibility
In most official Honda/Acura service catalogs, the oil filter for the 2.4L ILX is listed as 15400-PLM-A02. Regional catalogs and updated service bulletins can occasionally introduce slightly different part numbers, so it’s wise to confirm with a local dealer using your VIN.
Aftermarket compatibility and cross-referencing
There are several aftermarket filters that cross-reference to Honda/Acura 2.4L engines and fit the ILX. When shopping, ensure the filter is specified to fit Honda/Acura 2.4L engines and verify key dimensions (thread size, gasket diameter, and overall height) to ensure a proper seal and fit. If you’re unsure, ask a parts specialist or consult the dealer to confirm compatibility with your exact vehicle configuration.
How to confirm you’re getting the right filter
To be certain you have the correct part, follow these practical steps that apply to most 2020 ILX owners regardless of region or trim.
- Check the owner’s manual or service manual for the recommended oil filter part number and oil specification.
- Enter your vehicle’s VIN on the dealer parts website or contact the parts desk to pull the exact filter number for your car’s market.
- Cross-reference aftermarket filters with the manufacturer’s compatibility list to ensure Honda/Acura 2.4L fitment.
- Verify filter dimensions (thread size, gasket diameter, and overall height) match the original housing to avoid fitment issues.
- When in doubt, visit or call a dealership or trusted repair shop to confirm the correct part before purchasing.
Following these steps helps ensure you select the correct filter and avoid mismatches that could impact oil pressure or filtration.
