Where to Find the Air Filter on a 2001 Honda Accord

The engine air filter sits inside a black plastic air cleaner box in the engine bay—front passenger-side corner on 4‑cylinder models and front driver-side corner on V6 models. The car also has a separate cabin air filter located behind the glove box. Below is a detailed guide to identify both filters quickly and replace them if needed.

Engine Air Filter Location (2001 Accord, 4‑cyl vs. V6)

On U.S.-spec left-hand-drive 2001 Accords, Honda placed the engine intake air filter in a rectangular air cleaner housing with a large intake snorkel and an accordion-style rubber hose leading to the throttle body.

Exact placement by engine

Depending on your engine, look here:

• 2.3L 4‑cylinder (F23 series): Front passenger-side corner of the engine bay, just behind the headlight. The lid typically has spring clips (and sometimes screws) holding it down.
• 3.0L V6 (J30 series): Front driver-side corner behind the headlight. The lid may be retained by clips and/or 10 mm bolts.

These housings are black plastic boxes with a flat lid; the intake tube runs from the box toward the engine. If your Accord is right-hand-drive, the sides are generally mirrored.

How to replace the engine air filter

The steps below explain how to open the air cleaner box and change the panel filter safely without letting debris enter the intake.

1. Shut the engine off, set the parking brake, and open the hood.
2. Locate the air cleaner box (as noted above) and release its fasteners: flip the metal spring clips or remove the Phillips screws/10 mm bolts.
3. If space is tight, loosen the hose clamp on the intake tube to lift the lid higher (you usually don’t need to disconnect the hose fully).
4. Lift the lid, note the filter’s orientation, and remove the old rectangular filter element.
5. Wipe or gently vacuum leaves/sand from the box. Do not let debris fall into the open intake tube.
6. Install the new filter with the rubber gasket seated evenly around the edges (match the original orientation).
7. Reinstall the lid, ensure tabs are engaged, refasten clips/bolts, and retighten any hose clamp you loosened.

Once secured, check that the lid seals uniformly and that no tools or debris remain in the engine bay. A proper seal keeps unfiltered air from bypassing the element.

Cabin Air Filter Location (Interior)

Your 2001 Accord also uses a cabin air filter to clean air entering the HVAC system. It’s located behind the glove box and is separate from the engine air filter.

How to access and replace the cabin air filter

Follow these steps to reach and replace the cabin filter without removing the dashboard.

1. Open the glove box and empty it for access.
2. Push in the glove box side stops (or release the limiting arms) so the box can swing down further.
3. On many trims, remove the small horizontal brace or trim piece behind the glove box (usually two Phillips screws).
4. Locate the rectangular cabin filter door on the HVAC housing; press the side tabs and pull the door out.
5. Slide out the filter cartridges—there are typically two short trays placed end-to-end.
6. Install new cabin filters with the airflow arrows pointing down (match markings on the housing).
7. Reinstall the door, brace/trim, and return the glove box to its normal position by re-engaging the stops.

After replacement, run the fan to ensure there are no unusual noises; that confirms the filters are seated and nothing obstructs the blower.

Helpful Identifiers and Tips

These quick cues can help you confirm you’re looking at the right components and avoid common mistakes.

• The engine air box is the only large, sealed plastic box in the bay with a big rubber tube leading to the engine intake.
• 2001 Accords use a panel-style engine filter; no oiling is required. Avoid over-oiling aftermarket filters near intake sensors.
• If you’re unsure of engine type, check the under-hood emissions label; it will note 2.3L (4‑cyl) or 3.0L (V6).
• Typical service intervals: engine air filter every 15,000–30,000 miles (more often in dusty areas); cabin filter every 15,000–20,000 miles.

Using these clues and intervals helps keep both the engine and HVAC system breathing freely and operating efficiently.

Summary

The 2001 Honda Accord’s engine air filter is inside the black air cleaner box under the hood—front passenger-side on 4‑cylinder models and front driver-side on V6 models—while the cabin air filter is behind the glove box. Both are simple to access with basic hand tools and a few minutes of work.

How many air filters does a Honda Accord have?

A Honda Accord has two air filters: one for the engine and one for the cabin. The engine air filter cleans the air entering the engine, while the cabin air filter cleans the air entering the ventilation system for the occupants.
