The 2016 TLX uses different oil filters depending on the engine installed. The 2.4-liter inline-4 typically uses Honda/Acura part number 15400-PLM-A01, while the 3.5-liter V6 uses a different filter specific to that engine.
This article explains the two possible engines in the 2016 TLX, the corresponding OEM filter numbers, how to verify which one your car needs, and where to buy reliable replacements.
Engine options and corresponding oil filters
The TLX offered two engine choices in 2016. Each engine has its own compatible oil filter, so it’s important to identify which engine your car has before purchasing.
- 2.4L inline-4 engine — OEM oil filter part number 15400-PLM-A01. A common aftermarket cross-reference is Fram PH7317. This filter fits the 2.4L i-VTEC engine used in most 2016 TLX models with the 2.4L configuration.
- 3.5L V6 engine — OEM oil filter part number 15400-RAA-A02. This is the filter intended for the 3.5L V6 variant of the TLX; ensure your engine is the 3.5L to use the correct part.
Note: Filtration part numbers can vary by market or revision, so always confirm with your owner’s manual, the current filter on the car, or a dealer using your VIN. If you’re shopping aftermarket, use these OEM numbers as a reference point to find equivalent filters designed for the TLX engines.
How to verify which filter your TLX uses
To avoid buying the wrong filter, verify your engine and match the correct part number. Use the steps below to confirm.
- Check the engine under the hood or your vehicle’s documentation to identify whether your TLX is the 2.4L I-4 or the 3.5L V6.
- Look at the oil filter currently installed on the engine; the side of the filter may show a part number or brand that can be cross-checked with the OEM numbers above.
- If you’re unsure, locate your VIN and use it with a dealer or official parts catalog to determine the exact engine install and the correct oil filter number.
- When purchasing, consider buying from a reputable source (dealer, authorized parts retailer, or reputable aftermarket) and keep the receipt for future maintenance records.
Verifying in this way helps ensure you install the appropriate filter and maintain optimal engine protection for your TLX.
Where to buy and how to choose
Official OEM filters (15400-PLM-A01 for 2.4L; 15400-RAA-A02 for 3.5L) are widely available through Acura/Honda dealers and major parts retailers. Aftermarket options that advertise compatibility with Honda/Acura 2.4L or 3.5L engines can also be suitable, but always verify fitment for your specific vehicle and year. When in doubt, compare the filter’s thread size, gasket diameter, and overall dimensions to ensure a proper seal and adequate oil flow.
Summary
The 2016 Acura TLX may use two different oil filters depending on the engine. The 2.4L I-4 typically uses 15400-PLM-A01 (with Fram PH7317 as a common cross-reference), while the 3.5L V6 uses 15400-RAA-A02. Always verify with your VIN, check the existing filter, and consult the owner’s manual or dealer to confirm the exact part number before purchasing. Proper filtration supports engine longevity and reliable performance for your TLX.
