What oil filter your 2006 Accord uses and where to find it

The 2006 Honda Accord uses a cartridge-style oil filter located on top of the engine, not a spin-on filter screwed to the side. The filter sits inside a plastic housing with a black cap — you'll see it when ready when you open the hood, toward the back of the engine on the driver's side. This design matters because you don't unscrew the whole filter; you unscrew only the cap, pull out the filter element inside, and replace it.

Honda part number 15400-PLM-A01 is the OEM (original equipment manufacturer) filter for all 2006 Accords, whether you have the 2.0-liter or 3.0-liter engine. Aftermarket filters from Fram, Mobil 1, Bosch, and Purolator all make compatible replacements that fit the same housing. The filter element itself costs between $8 and $20 depending on the brand; the OEM Honda filter runs closer to $15 to $18. You can find this part at any auto parts store, online retailers, or a Honda dealership.

Key Takeaways

  • The 2006 Accord has a cartridge filter on top of the engine with a removable cap, not a spin-on filter you screw off the side.
  • Honda part number 15400-PLM-A01 is the correct OEM filter for all 2006 Accord models and engine sizes.
  • You need an oil filter wrench to remove the cap — a standard 74mm or 86mm socket wrench works, or a dedicated cartridge filter wrench from any auto parts store.
  • Always replace the rubber O-ring seal on the cap when you replace the filter; reusing the old one causes leaks.
  • The job takes 10 to 15 minutes once you have the right wrench and takes no special tools beyond that.

Tools and supplies you'll need

Beyond the filter itself, you need an oil filter wrench to remove the cap. A 74mm or 86mm socket wrench fits the cap on the 2006 Accord — most people use a 74mm. If you don't have a socket that size, a dedicated cartridge filter wrench (a metal cup with a handle, sold at any auto parts store for $8 to $15) works just as well and is easier to grip. You'll also need a drain pan to catch oil that spills when you open the housing, and a clean rag or paper towels.

The one part many people forget is the rubber O-ring seal that comes with the new filter element. This seal sits on the cap and prevents oil from leaking around the housing. If you reuse the old seal, it hardens and no longer seals properly, and you'll see oil dripping from the cap within days. Most replacement filters come with a new O-ring in the box, but check before you buy. If yours doesn't include one, Honda sells the O-ring separately (part number 91301-ZW9-003) for a few dollars. Having this seal on hand before you start prevents a trip back to the store mid-job.

Step-by-step replacement process

Start with the engine cold or warm but not hot — you don't want to burn yourself on the housing. Locate the black plastic cap on top of the engine. Place your drain pan underneath it to catch the small amount of oil that will spill. Use your 74mm socket or filter wrench to turn the cap counterclockwise until it comes free; it will take a few turns before it breaks loose, then unscrew by hand the rest of the way.

Once the cap is off, you'll see the filter element inside — a white or yellow cylindrical piece. Pull it straight up and out. Wipe the inside of the housing clean with a rag to remove any debris or old filter material. Take the new filter element and slide it into the housing, making sure it sits flat on the bottom. Screw the cap back on by hand first, then use your wrench to tighten it snugly — you don't need to crank hard, just firm enough that it won't come loose. Wipe away any spilled oil with your rag, close the hood, and you're done.

Common mistakes that cause leaks

The most frequent problem is forgetting to replace the O-ring seal on the cap. The old seal gets compressed and hardens over time, so it no longer grips the housing. When you screw the cap back on with the old seal, oil seeps out around the edges within a day or two. Always inspect the cap before you reinstall it — if the rubber ring looks cracked, flattened, or hard, replace it with the new one that came in your filter box. This single step prevents the majority of post-replacement leaks.

The second common mistake is over-tightening the cap. The housing is plastic, and if you crank the wrench too hard, you can crack it or strip the threads inside. Tighten until you feel resistance, then give it another quarter-turn. If oil still leaks after a day, the problem is almost always the O-ring, not the tightness. A cracked housing is expensive to replace, so restraint here saves money.

When to replace the filter

Honda recommends replacing the oil filter every time you change the oil. For a 2006 Accord, that's typically every 3,000 to 5,000 miles if you use conventional oil, or every 7,500 to 10,000 miles if you use synthetic oil — check your owner's manual for the exact interval for your model. Some owners stretch intervals longer with synthetic, but the filter should still be replaced at the same time as the oil change.

If you notice oil dripping from under the hood near the engine, or if your oil pressure warning light comes on, check the filter cap first. A loose cap or failed O-ring is often the culprit and is much cheaper to fix than engine damage from low oil pressure. Catching a leak early prevents damage to other engine components.

Disposal of the old filter

The filter element itself contains a small amount of oil, so don't throw it in the trash. Most auto parts stores that sell filters will take the old element back for free — Autozone, O'Reilly, NAPA, and Advance Auto Parts all have take-back programs. If you changed the filter at home, bring the old element with you when you buy the new one and ask them to dispose of it.

Some recycling centers also accept oil filters, though you may need to call ahead to confirm. Never pour the small amount of oil from the old filter down a drain — it contaminates water supplies. Letting the old filter sit in your drain pan for a few minutes before disposal allows most of the oil to drain out, making it easier to handle and dispose of responsibly.

Frequently Asked Questions

Can I use a spin-on filter instead of the cartridge filter?

No. The 2006 Accord is designed for a cartridge filter only. Spin-on filters don't fit the housing, and adapters to make them work are not reliable. Stick with the cartridge design that came on your car.

What if I can't get the cap off with a wrench?

The cap may be stuck if the previous owner over-tightened it or if it's been on for a long time. Tap the wrench gently with a hammer to break the seal, or explore penetrating oil (like WD-40) around the cap and wait 15 minutes before trying again. If it still won't budge, a cartridge filter wrench with a longer handle gives you more leverage than a socket.

Do I need to fill the new filter with oil before installing it?

No. Unlike spin-on filters, cartridge filters don't need to be pre-filled. Just drop the dry element into the housing and screw the cap back on. The oil will flow through it once the engine starts.

How much oil will spill when I open the housing?

Usually just a few ounces — enough to fill a drain pan partway, but not a large amount. If a lot of oil pours out, you may have a leak elsewhere in the system. A small amount is normal and expected.

Is there a difference between Honda OEM filters and aftermarket brands?

OEM Honda filters meet Honda's exact specifications and typically cost $15 to $18. Quality aftermarket brands like Fram, Mobil 1, and Bosch cost $8 to $15 and perform similarly for most owners. The difference is minimal for routine maintenance, though some prefer OEM for peace of mind on older engines.
