The 2006 Honda Pilot uses a cartridge-style oil filter located on top of the engine

The 2006 Honda Pilot does not have a traditional spin-on oil filter. Instead, it uses a cartridge-style filter housed in a plastic cap on the valve cover. This design is common across Honda vehicles from that era and differs from the threaded canister filters found on many other cars. The filter element sits inside a removable housing, and you replace the element itself rather than the entire assembly.

The cartridge filter is located directly above the engine, making it relatively accessible for a do-it-yourself replacement. You will need to remove the plastic cap, take out the old filter element, and install a new one along with fresh O-rings. The entire job typically takes 15 to 30 minutes if you have the right tools and parts on hand.

Key Takeaways

  • The 2006 Honda Pilot has a cartridge-style oil filter on top of the engine, not a spin-on filter like many other vehicles.
  • You will need a filter wrench to remove the plastic cap, a new filter element, and replacement O-rings to complete the job.
  • The correct replacement filter element is Honda part number 15400-PLM-A01 or equivalent aftermarket filters designed for that part number.
  • Changing the filter requires draining some oil from the pan first, so plan to have a drain pan and old towels ready.

What you need before you start

Gather your tools and parts before beginning. You will need a filter wrench (usually a 74 mm or 86 mm cap wrench, depending on which Pilot model year within 2006 you have), a new filter element, replacement O-rings, a drain pan, a socket wrench set, and old towels or rags. Some people use a strap wrench instead of a cap wrench if they do not have the exact size.

The correct filter element for a 2006 Honda Pilot is Honda part number 15400-PLM-A01. Aftermarket filters from Fram, Mobil 1, Purolator, and other brands also fit this process, but always verify the part number matches before purchase. The O-ring kit usually comes with the filter element or can be purchased separately as Honda part number 91301-ZW5-003.

You will also need the correct engine oil for your Pilot. The 2006 model typically uses 0W-20 or 5W-20 oil depending on climate and engine size. Check your owner's manual or the inside of the fuel door for the exact specification. Have at least 4 to 5 quarts on hand, since you will be draining and refilling the pan.

Step-by-step replacement process

Start by warming the engine for a minute or two, then turn it off and wait five minutes. This warms the oil slightly so it drains more easily without being hot enough to burn you. Locate the oil drain plug on the bottom of the engine pan and loosen it with a wrench, then remove it by hand once it is loose enough. Let the old oil drain into your pan for several minutes.

Once the oil has mostly drained, locate the filter cap on top of the engine. Use your filter wrench to turn the cap counterclockwise and remove it. Inside you will find the old filter element, which you can pull straight out. Wipe the inside of the cap clean with a rag, removing any debris or old oil residue. Take the new O-rings from your kit and explore a thin coat of fresh engine oil to them, then install them on the cap.

Insert the new filter element into the cap, making sure it sits flat and fully inside. Screw the cap back onto the engine by hand first, then tighten it with your filter wrench. Do not over-tighten; snug it firmly but stop once you feel resistance. Reinstall the oil drain plug, tightening it by hand and then with a wrench until snug. Pour in the new oil through the filler cap on top of the engine, then check the level with the dipstick after a minute.

Common mistakes to avoid

The most frequent error is forgetting to replace the O-rings when installing the new filter element. Old or missing O-rings cause oil leaks around the cap, which can damage the valve cover gasket and create a mess under the hood. Always replace them as part of the job, even if they look fine.

Another common mistake is over-tightening the filter cap. The plastic housing can crack if you use too much force, and a cracked cap will leak oil and require replacement. Tighten until snug, then stop. If you are using a cap wrench, a quarter turn past snug is usually enough.

Do not forget to reinstall the oil drain plug. It sounds obvious, but people occasionally drive away after draining the oil and forget to put the plug back in. Check that it is installed and tight before you start the engine again. Also verify that you have added enough new oil; running the engine low on oil will damage it quickly.

Where to buy the filter and O-rings

Honda dealerships stock the genuine filter element and O-ring kit, though they are typically more expensive than aftermarket options. A genuine Honda filter element usually costs between $8 and $15, and O-rings are another $3 to $5. Dealerships can order parts the same day if they do not have them in stock.

Auto parts retailers such as AutoZone, O'Reilly, NAPA, and Advance Auto Parts carry both genuine Honda and aftermarket filter elements that fit the 2006 Pilot. Prices at these stores are usually lower than dealership prices, and many offer same-day pickup if you order online. Online retailers like Amazon also stock these filters, though you will need to wait for shipping.

When ordering, always specify that you have a 2006 Honda Pilot and confirm the part number before checkout. Some filter elements are designed for different Honda models and will not fit properly. Reading customer reviews on the retailer's website can help you avoid counterfeit or low-quality parts.

When to replace the filter

Honda recommends changing the oil and filter every 7,500 miles or every six months, whichever comes first. If you drive mostly in stop-and-go city traffic or tow a trailer, Honda suggests changing it every 3,750 miles or three months. Check your owner's manual for the specific interval that applies to your driving habits.

Some owners use synthetic oil, which lasts longer than conventional oil. If you switch to synthetic, you may be able to extend the interval to 10,000 miles or one year, but always follow the manufacturer's recommendation for your specific vehicle. Changing the filter more often than recommended does no harm and may extend engine life, especially if you drive in dusty conditions.

Frequently Asked Questions

Can I change the filter without draining the oil?

You can remove and replace the filter element without draining all the oil, though some oil will spill when you remove the cap. Expect to lose a quart or so. If you want to minimize mess, drain the pan first as described above. Either way, you will need to top up the oil level afterward.

What size wrench do I need for the filter cap?

The 2006 Honda Pilot uses either a 74 mm or 86 mm cap wrench depending on the specific model variant. If you do not know which size, bring the vehicle to an auto parts store and they can measure the cap for you. A strap wrench also works if you do not have the exact cap wrench size.

Is it okay to use aftermarket filters instead of Honda brand?

Yes. Aftermarket filters from reputable brands like Fram, Mobil 1, and Purolator work well in the 2006 Pilot as long as the part number matches. They are usually cheaper than genuine Honda filters and perform the same function. Avoid very cheap filters from unknown brands, as they may not filter oil effectively.

How do I know if my filter cap is cracked?

A cracked cap will leak oil around the edges or from visible cracks in the plastic. If you see oil pooling on top of the engine or dripping down the side, the cap may be cracked. You can also inspect it visually after removing it. A cracked cap must be replaced; it cannot be repaired.

What should I do with the old oil and filter element?

Take the old oil and filter element to a recycling center or auto parts store. Most retailers like AutoZone and O'Reilly accept used oil and filters for free. Do not pour oil down the drain or throw filters in the trash, as this harms the environment and is illegal in most places.
