For a 2004 Honda Civic LX, the oil filter is a cartridge-type filter designed for the 1.7-liter D-series engine. The standard Honda Genuine filter is usually 15400-PLM-A01 (some production runs use 15400-PLM-A02); confirm the exact part with a dealer or by looking up your VIN.
In this article, we break down how to identify the right filter, where to find the part numbers, and how to replace it safely, including guidance on aftermarket cross-references and installation steps.
Filter type and how it sits in the engine
The 2004 Civic LX uses a cartridge-style oil filter that sits inside a housing on the engine. When you replace it, you’ll typically remove the end cap of the housing, replace the cartridge and its O-ring, and reseal the housing before adding fresh engine oil. Always replace the O-ring and lightly lubricate it with clean oil before reinstalling.
OEM part numbers and cross-compatibility
To ensure you get the exact filter for your car, verify the part number via Honda’s official parts lookup or a trusted parts retailer using your VIN or engine code. The commonly cited Honda Genuine filter for this generation Civic is around 15400-PLM-A01, with some production dates using 15400-PLM-A02. Aftermarket filters from brands such as Wix, Bosch, Fram, and Purolator offer cross-references that fit the 1.7L D-series engine, but you should double-check compatibility before purchase.
What to check on the filter and when buying
Look for a cartridge-style design that matches the engine’s housing and ensure you also get a new O-ring seal. If you’re unsure, use a reputable cross-reference tool or ask the parts counter to confirm it matches your exact Civic’s year, trim, and VIN.
- The oil filter for this Civic is cartridge-based; do not use filters intended for different engines or non-cartridge designs without a verified cross-reference.
- Honda Genuine part numbers commonly cited include 15400-PLM-A01, with some production runs using 15400-PLM-A02; verify the exact number for your vehicle.
- Aftermarket cross-references exist for this model; confirm compatibility with your VIN and engine code before purchasing.
In practice, the most reliable route is to check your VIN with a Honda dealer or a trusted parts retailer. This ensures you receive the correct filter for your specific production date and market.
How to replace the oil filter safely
Replacing the oil filter is part of a standard oil-change procedure. You’ll drain the old oil, remove the old cartridge and O-ring, install a new filter with a fresh O-ring, and refill with the recommended oil. Properly dispose of the old oil and recycle the filter according to local regulations.
Preparation and steps
Before you begin, gather the necessary tools, a new cartridge oil filter, a new O-ring, fresh engine oil, and a drain pan. Follow the steps below and consult your owner’s manual for torque specifications and oil capacity specific to your vehicle.
- Warm up the engine, place a drain pan beneath the oil pan, and remove the drain plug to drain the used oil.
- Remove the oil filter housing cap or accessible end cap, take out the old cartridge, and replace with a new cartridge and fresh O-ring.
- Lubricate the new O-ring with a light coating of new engine oil, reseal the housing, and torque to the manufacturer’s specification.
- Refill with the correct amount and grade of engine oil, start the engine, and check for leaks around the filter housing.
Always use the oil grade recommended in your owner's manual (often 5W-20 for many Hondas of this era, but verify for your local climate and mileage). If you’re unsure about the exact torque specs or the correct filter, consult a professional technician or a Honda service center.

When replacing, follow the standard oil-change process and use the recommended oil grade from your manual. If in doubt, seek professional assistance to ensure a proper fit and seal.
