The typical oil filter for most 2003 Honda Civics with the common 1.7-liter engine is Honda part number 15400-PLM-A01. If your Civic uses the 2.0-liter engine, the filter differs and you should verify the exact part number for your model.
In 2003, the Civic lineup included several trims that spanned two engine families. The LX and EX models commonly used the 1.7-liter D-series engine, while the high-performance Si used a 2.0-liter K-series engine. Because oil filter compatibility depends on the engine, it’s important to identify your engine code or trim to ensure you order the correct part.
Engine options in the 2003 Civic
To understand which filter you need, start by identifying the engine in your car. The 1.7-liter D-series is typical for most LX/EX Civics from that year, whereas the Si uses a different 2.0-liter setup. The oil filter part number follows the engine type, not solely the year, so verification is essential if you’re unsure.
To help you identify the right filter, consider your engine type and trim, and compare against official references from Honda or a trusted parts retailer.
- 1.7L D-series (LX/EX, common in 2003 Civics): Honda Genuine Oil Filter 15400-PLM-A01 (some production runs may use 15400-PLM-A02). Aftermarket cross-references often include Fram PH7317, Wix 51515, and Bosch 3330. Verify by VIN or by checking the filter currently on the engine.
- 2.0L K-series (Si, if equipped): This variant uses a different filter from the 1.7L D-series. Confirm the exact part number via VIN, owner’s manual, or a parts catalog to ensure compatibility.
Conclusion: For most 2003 Civics with the common 1.7L engine, the correct filter is the Honda 15400-PLM-A01. If your car is the Si with the 2.0L engine, consult the manufacturer’s catalog or a parts professional to confirm the exact filter model.
How to confirm the exact filter at a parts counter
If you’re ordering in person or online and want to avoid the wrong part, follow these steps to confirm the correct oil filter for your 2003 Civic.
- Check your engine code or trim label to determine whether you have the 1.7L D-series or the 2.0L K-series.
- Locate the existing oil filter on your engine and read any part numbers or identifiers printed on it.
- Have your VIN handy when asking for a cross-reference at a parts store or online catalog.
- Ask for Honda Genuine 15400-PLM-A01 (or the appropriate K-series equivalent) and cross-reference with recommended aftermarket filters if you prefer a third-party option.
- Double-check the fitment in the store’s system or on the retailer’s website before purchasing.
In practice, most 2003 Civics that aren’t Si will use 15400-PLM-A01, with potential alternate sub-variants depending on production date. Always verify using your vehicle’s VIN or by inspecting the current filter and consulting a reliable parts database.
Summary
For the typical 2003 Honda Civic with a 1.7L engine, the standard oil filter is Honda part number 15400-PLM-A01, with some production runs using -A02. Si models with the 2.0L engine require a different filter, so confirm via VIN or official parts catalogs. When in doubt, consult your owner’s manual or a trusted parts retailer to ensure exact compatibility and a proper seal during installation.
