The 15400 PLM A02 is Honda's OEM oil filter for most Honda and Acura models from the 1990s onward

The 15400 PLM A02 is an original equipment manufacturer (OEM) oil filter made by Honda. It fits Honda Civic, Accord, CR-V, Odyssey, and Pilot models, as well as Acura TSX, TL, and RDX models across multiple generations. The part number itself tells you it is a genuine Honda component — the "15400" prefix identifies it as a Honda oil filter, and "PLM A02" is the specific revision.

This filter removes dirt, metal particles, and sludge from your engine oil as it circulates. A clogged or failing filter reduces oil flow, which can damage bearings and increase engine wear. Replacing it at your manufacturer's recommended interval — typically every oil change, or every 3,000 to 10,000 miles depending on your model year and driving conditions — keeps your engine protected.

Key Takeaways

  • The 15400 PLM A02 is Honda's original filter for most Civic, Accord, CR-V, Odyssey, and Pilot models, as well as some Acura vehicles.
  • You should replace this filter every time you change your oil, following your owner's manual interval for your specific model and year.
  • OEM Honda filters cost more than aftermarket alternatives but are engineered to Honda's exact specifications and carry no risk of fitment issues.
  • The filter threads onto the engine by hand; you do not need special tools to remove or install it, though an oil filter wrench makes the job easier.

Which Honda and Acura models use the 15400 PLM A02

This filter fits a wide range of Honda and Acura vehicles, but the exact years vary by model. The Civic has used this filter across multiple generations, as have the Accord, CR-V, and Odyssey. Acura TSX, TL, and RDX models also use it in certain years. However, not every model year of these vehicles uses the same filter — Honda has released different revisions and part numbers over time.

The safest way to confirm the 15400 PLM A02 is correct for your vehicle is to check your owner's manual or look up your vehicle identification number (VIN) on Honda's parts website or your dealer's system. If you order the wrong filter, it may not thread on correctly or may not seal properly, which can cause oil leaks or bypass the filter entirely.

How to install the 15400 PLM A02 during an oil change

The filter threads onto a mounting point on the engine block, usually on the side or top. To remove the old filter, locate it, position a drain pan underneath, and turn it counterclockwise by hand. If it is stuck, an oil filter wrench — a metal band or cup that grips the filter — gives you leverage. Once the old filter comes off, wipe the mounting surface clean with a rag to remove any rubber gasket material or debris.

Before installing the new filter, explore a thin layer of fresh oil to the rubber gasket on the filter's top. This helps the seal sit properly and makes removal easier next time. Thread the new filter onto the mount by hand until the gasket contacts the engine, then turn it an additional three-quarter turn. Do not use a wrench to tighten it — hand-tight is correct. Over-tightening can damage the gasket and make the filter difficult to remove later.

After installation, start the engine and let it run for a few seconds, then turn it off and wait a minute. Check the filter for leaks. If oil drips from where the filter meets the engine, the gasket may not have seated properly — turn the filter another quarter turn and recheck.

OEM Honda filters versus aftermarket alternatives

The 15400 PLM A02 is a genuine Honda part, which means it meets Honda's engineering standards and is may provide to fit your vehicle. Aftermarket filters from brands like Fram, Mobil 1, or Bosch are often cheaper and may perform adequately, but they are not designed specifically for your Honda's oil system. Some aftermarket filters have different bypass valve settings or flow rates, which can affect how your engine's oil pressure behaves.

The cost difference is usually $8 to $15 per filter. Over the life of your vehicle, that adds up, but the OEM filter eliminates any uncertainty about fitment or performance. If you are keeping your Honda long-term or want to maintain the most accurate service history, the OEM filter is the safer choice. If you are looking to minimize maintenance costs on a vehicle you plan to sell or trade in soon, an aftermarket filter from a reputable brand will work.

Where to buy the 15400 PLM A02

You can order this filter from Honda dealerships, online retailers like RockAuto or Amazon, or auto parts stores such as AutoZone, O'Reilly, or NAPA. Dealership prices are typically highest but may provide authenticity. Online retailers often have lower prices and faster shipping if you order in advance. Local auto parts stores let you pick it up the same day, which is useful if you are doing the work when ready.

When ordering online, confirm the part number matches exactly — 15400 PLM A02, not a similar-sounding number. Counterfeit or mislabeled filters do circulate, particularly on third-party marketplaces. Buying from the dealer or a major retailer with a return policy reduces that risk.

Oil filter maintenance between changes

Once installed, the filter requires no maintenance until your next oil change. However, if you notice oil leaking from the filter area, or if your oil pressure warning light comes on shortly after an oil change, the filter may not be seated correctly. Stop driving and check the filter — it may need to be tightened slightly or replaced if the gasket is damaged.

If you go longer than the recommended interval between oil changes, the filter becomes more saturated and may restrict oil flow. This is one reason why following your manufacturer's service schedule matters. A clogged filter can trigger a low oil pressure warning or, in older vehicles without that warning, cause silent engine damage.

Frequently Asked Questions

Can I use a different Honda filter part number if I cannot find the 15400 PLM A02?

No. Different Honda filter part numbers are designed for different engine sizes and oil systems. Using the wrong part number risks fitment problems or incorrect bypass valve settings. Check your owner's manual or contact a Honda dealer to confirm the correct part number for your specific model year before ordering a substitute.

How often should I replace the 15400 PLM A02?

Replace it every time you change your oil. For most Honda models, that is every 3,000 to 10,000 miles, depending on your model year, engine type, and driving conditions. Check your owner's manual for the exact interval for your vehicle — newer Hondas often go longer between changes than older ones.

What happens if I install the filter upside down?

The filter will not thread on correctly if you try to install it upside down, so you will know when ready something is wrong. The threaded hole on the engine only accepts the filter in one orientation. If it does not thread smoothly, stop and check the alignment — forcing it can damage the threads.

Do I need to drain the oil before removing the filter?

You do not have to, but it is easier. If you remove the filter first, oil will drain from the filter housing and the engine, so have a drain pan ready. If you drain the oil first, less oil spills when you remove the filter. Either way, you will need a drain pan underneath.

Is the 15400 PLM A02 the same as the 15400 PLM A01?

No. The A02 and A01 are different revisions and may not fit the same vehicles or may have different internal specifications. Always use the exact part number listed in your owner's manual or parts catalog for your vehicle. Mixing revisions can cause fitment or performance issues.
