You can replace a Honda Pilot air filter yourself in about 10 minutes with no tools
The engine air filter on a Honda Pilot sits in a plastic box under the hood and slides out sideways. You pop two clips, lift the lid, pull out the old filter, drop in a new one, and close it back up. The whole job takes longer to find a parking spot than to do the work. A new filter costs $15 to $30 depending on the brand and model year.
Most Pilots need a new air filter every 15,000 to 30,000 miles, though that varies by how much dust and pollen your area gets. If you drive in sandy or very dirty conditions, check it more often. The filter gets darker and thicker as it collects debris, and when it's clogged, your engine has to work harder and uses more fuel.
Key Takeaways
- The air filter box is located on the driver's side of the engine bay, under the hood, and requires no tools to open.
- You need only the replacement filter itself — no special equipment, no drain pan, no fasteners to track.
- The job takes about 10 minutes and involves popping two clips, lifting the lid, and sliding the old filter out horizontally.
- Replacement filters cost between $15 and $30, and OEM Honda filters are usually more expensive than aftermarket brands that fit just as well.
- Check your owner's manual or the filter itself for the correct part number, because different model years use different sizes.
Locate the air filter box under your hood
Open your hood and look toward the driver's side of the engine bay, near the front wheel well. You'll see a black plastic box about the size of a small toaster. This is the air intake box. On most Pilots, it sits to the left of the engine when you're facing the front of the car.
If you're not sure you're looking at the right thing, trace the large rubber hose that connects to the top of the engine — it leads to the air box. The box itself is rectangular and has a seam running around the middle where the lid meets the base. Two black clips stick out from the sides of the lid.
Open the air filter box by releasing the two clips
Look at both sides of the air box lid. You'll see a black plastic clip on each side — they look like small handles. Push or pull each clip outward (the direction varies slightly by model year, but they move away from the center). You don't need force; they're designed to release by hand.
Once both clips are released, the lid lifts straight up. Set it aside on a clean surface so you don't drop anything into the open box. Some Pilots also have a hose clamp or a single bolt holding part of the intake, but most just have the two clips.
Remove the old filter and note its size
The filter sits flat inside the box. It's usually white or light tan on the outside, and it may look gray or dark if it's been in the car for a while. Grab it by the edges and slide it straight out toward you — it comes out horizontally, not vertically.
Before you throw it away, look at the frame of the old filter. You'll see a part number printed on the cardboard edge. Write this down or take a photo. This number tells you exactly which replacement to buy. If you can't find the number on the filter, check your owner's manual under "air filter" or "engine air filter" — it will list the part number for your model year.
Buy the correct replacement filter for your model year
Honda Pilots from different years use different filter sizes, so you must match your model year. A 2009 Pilot takes a different filter than a 2015 Pilot, even though they look similar. The easiest way is to take the old filter's part number to an auto parts store — they can match it when ready.
You have two main options: OEM Honda filters (made by Honda) or aftermarket filters (made by other companies like Fram, Bosch, or Mann). OEM filters usually cost $25 to $35. Aftermarket filters run $15 to $25 and work just as well; they're not inferior, just made by a different manufacturer. Both types fit the same way and last the same amount of time.
Install the new filter and close the box
Slide the new filter into the box the same way the old one came out — horizontally, with the frame edges aligned with the grooves inside the box. It should slide in smoothly and sit flat. The filter frame should fit snugly so it doesn't rattle, but you shouldn't have to force it.
Once the filter is seated, place the lid back on top of the box and push it down until you hear or feel a click. Then push the two clips back in from the sides until they lock. You'll feel them snap into place. Close your hood, and you're done. No need to start the engine or do anything else — the car will run normally right away.
Know when to check or replace your filter
Most Honda Pilots need a new air filter every 15,000 to 30,000 miles. If you drive in a dusty area, tow a trailer, or drive mostly on unpaved roads, check it every 10,000 miles. You can do this by opening the box and looking at the filter without removing it — if it looks dark gray or black instead of white, it's time to replace it.
Some signs that your filter is clogged include a slight drop in fuel economy, a rough idle, or the check engine light coming on. These aren't emergencies, but they mean the filter is working hard and should be replaced soon. Replacing it early won't hurt anything; it just means you're being cautious.
Frequently Asked Questions
Do I need to reset anything after I change the air filter?
No. The air filter change doesn't affect any computer settings or sensors. Your Pilot will run normally right away. If the check engine light was on because of a clogged filter, it may take a few miles of driving for the light to turn off on its own.
Can I clean and reuse my old air filter instead of replacing it?
You can rinse a paper air filter with water and let it dry, but it won't restore it to like-new condition. A cleaned filter still has trapped dust inside the paper that won't come out. Replacement filters are cheap enough that cleaning is usually not worth the effort — just buy a new one.
What if I buy the wrong size filter by mistake?
It won't fit into the box, or it will fit loosely and rattle. If this happens, take it back to the store with your receipt and exchange it for the correct part number. Always double-check the part number before you leave the store.
Is there a cabin air filter I should replace at the same time?
Yes. Honda Pilots also have a cabin air filter that cleans the air coming through your vents. It's located behind the glove box and takes about 15 minutes to replace. You can do both filters on the same day if you want, but they're separate jobs with different part numbers.
Can I take my Pilot to a shop instead of doing this myself?
Yes, but you'll pay labor costs on top of the filter price — usually $50 to $100 total. Since the job takes 10 minutes and requires no special tools, most people find it easier and cheaper to do it at home.
