The 2004 Honda Pilot uses the Honda OEM oil filter part number 15400-PLM-A01.
The 2004 Pilot runs a 3.5-liter V6 (J35) and shares its basic filtration setup with other 3.5L Honda engines. While the standard OEM filter is 15400-PLM-A01, some parts catalogs list a related cross-reference that may appear as 15400-PLM-A02 in certain batches or regions. Always verify by checking the filter packaging or looking up the vehicle by VIN to ensure compatibility. In addition to the filter, using the correct oil type and capacity is essential for proper lubrication and engine longevity.
Part numbers and compatibility
Before listing the main references, it helps to know what to look for when shopping for a replacement filter. The goal is to match the exact filter size, thread size, and gasket seal to your 2004 Pilot’s engine.
OEM filter
- Honda OEM filter: 15400-PLM-A01 (for the 3.5L V6 used in the 2003–2008 Pilot).
Cross-reference / aftermarket options
- Some catalogs show a related cross-reference such as 15400-PLM-A02; verify compatibility with your VIN or by matching filter dimensions and gasket.
In all cases, confirm fit by checking the packaging or performing a VIN-based parts lookup. This helps prevent muffed threads or improper sealing that can lead to leaks.
Oil type and capacity
Alongside the correct filter, using the right oil is critical. For the 3.5L V6 in the 2004 Pilot, Honda typically recommends 5W-20 engine oil for normal driving, with an approximate oil capacity of 4.5 quarts when changing the filter. Climate, driving conditions, and manufacturer updates can influence these specs, so always consult the owner's manual or a trusted parts database for your exact vehicle configuration.
Using a high-quality oil and performing regular changes helps protect the engine and maintain performance over time.
Replacement steps (quick guide)
Following a standard oil-change procedure ensures a proper seal and clean lubrication. Use this as a quick reference; consult the factory service manual for detailed steps if needed.
- Warm the engine, drain the old oil from the pan, and remove the old filter.
- Prepare the new filter by applying a light film of oil to the gasket, then thread it by hand until snug. Avoid overtightening.
- Refill with the recommended oil (about 4.5 quarts for a full change with a new filter, but check your manual). Check for leaks after starting the engine and rechecking the oil level with the dipstick.
- Dispose of used oil and the old filter properly according to local regulations.
Proper installation and accurate oil levels help ensure reliable operation and prevent premature engine wear.
