The 2005 Acura TL uses a cartridge-style oil filter, and the common OEM part is Honda 15400-PLM-A01. In practice, you’ll want either that exact cartridge or a widely compatible aftermarket cartridge that matches the TL’s filter design.
Overview of the TL’s oil filter system
On the 2005 TL, equipped with the 3.2-liter J-series V6, the oil filter is a replaceable cartridge that sits inside a small housing on the engine. The exact part number can vary by production date, but 15400-PLM-A01 is the most frequently listed OEM option for this generation. Some catalogs also show a similar suffix (such as 15400-PLM-A02) for certain production runs. Always verify fitment against your vehicle’s VIN or parts diagram to avoid mismatches.
Common filter options
To help you shop, here are the typical options you’ll encounter when selecting a filter for a 2005 TL.
- OEM Honda/Acura cartridge filter: 15400-PLM-A01 (most 2004–2008 TLs).
- OEM revised option: 15400-PLM-A02 (appears on some production runs).
- Aftermarket cartridge filters from major brands that fit the TL’s J-series engine (verify fitment before purchasing).
Choosing the right one typically comes down to matching the part number to your car’s VIN and confirming fit with the retailer’s catalog or a trusted parts diagram.
How to replace or verify the correct filter
If you’re planning a DIY oil change, confirm you have the correct replacement cartridge and a new O‑ring seal, then follow a standard cartridge-filter replacement procedure. The TL’s filter sits in a housing on the engine and requires removing the housing cap, extracting the old cartridge, and inserting a new one before resealing the cap and topping up oil.
Steps at a glance
Before you start, gather the right tools and the correct replacement cartridge.
- Warm the engine, then secure the vehicle on level ground and engage the parking brake.
- Drain the old oil from the oil pan.
- Remove the filter housing cap and pull out the old cartridge; inspect the O-ring for wear.
- Install the new cartridge, replace the O-ring if needed, reseal the housing cap, and refill with fresh oil to the recommended level.
Always consult your owner's manual or a trusted parts catalog to confirm the exact steps for your specific vehicle model year and trim, as minor variations can exist.
Final notes and recommendations
For most TL owners, using the OEM Honda/Acura cartridge filter (15400-PLM-A01) or a clearly compatible aftermarket cartridge is sufficient. If you’re unsure, ask a dealer or trusted shop to verify the correct part number for your VIN before purchasing.
Summary: The 2005 Acura TL uses a cartridge-style oil filter, most commonly Honda part 15400-PLM-A01. Some production runs may use a similar 15400-PLM-A02. Choose OEM or an equivalent aftermarket cartridge that matches the TL’s design and size, and verify fit with your VIN. Regular oil changes according to manufacturer recommendations are essential for engine health.
