Yes. You can replace both the engine air filter and the cabin (HVAC) air filter on a 2023 Honda Pilot yourself, typically in under an hour with basic tools.
In this guide, you’ll learn where to find each filter, what tools (if any) you’ll need, step-by-step instructions for the engine and cabin filters, and tips on maintenance intervals and choosing the right replacement parts.
Engine air filter
The engine air filter sits in a rectangular plastic air box in the engine bay. Replacing it is a straightforward, clip- or screw-based process that doesn’t require specialized equipment.
What you'll need
Before you start, gather the replacement engine air filter and any basic tools that your housing may require (a screwdriver or a small flathead for retaining clips).
- Replacement engine air filter (OEM or high-quality aftermarket)
- Flathead screwdriver or Phillips screwdriver (if clips or screws are used)
- Clean cloth or rag
- Optional: flashlight for better visibility
Having the right parts and tools on hand helps you complete the job quickly and reduces the chance of redoing any steps.
Steps to replace the engine air filter
Follow these steps to replace the engine air filter in your 2023 Pilot.
- Park the vehicle on a flat surface, set the parking brake, and turn off the engine. Open the hood and locate the engine air filter housing, usually a rectangular black plastic box toward the front of the engine bay.
- Release the housing cover by undoing the retaining clips or removing the screws that secure it.
- Lift the cover off and carefully remove the old air filter. Check the filter for dirt and signs of damage; avoid dropping debris into the box.
- Wipe the inside of the housing with a clean cloth to remove dust or debris.
- Inspect the new filter for the correct orientation. Most filters have an arrow indicating the direction of airflow; align the filter so the arrows point toward the engine.
- Place the new filter snugly into the housing and reseat the cover, ensuring all clips or screws are secure.
- Close the hood and, if desired, restart the engine to verify it runs smoothly and there are no unusual sounds or air leaks around the housing.
After completing these steps, you’ve successfully replaced the engine air filter. A properly seated filter helps improve engine efficiency and fuel economy.
Cabin air filter
The cabin air filter is located behind the glove box in the HVAC housing. Replacing it helps maintain interior air quality and HVAC performance.
What you'll need
For the cabin air filter replacement, you’ll typically need only the new cabin filter. Some models may require a small flathead screwdriver to release clips or push tabs.
- Cabin air filter (correct part for the 2023 Pilot)
- Optional: small screwdriver for releasing clips
- Flashlight for visibility
- Clean cloth for wiping dust from the housing
Having the replacement on hand will make the process quick and clean, with minimal disassembly.
Steps to replace the cabin air filter
Follow these steps to replace the cabin air filter in your 2023 Pilot.
- Open the glove box and clear contents. If the glove box has dampers or stoppers, gently release them so the box can drop down enough to access the filter housing behind it.
- Locate and remove the cabin filter housing cover. It is typically held in place with tabs or small screws.
- Remove the old cabin filter and inspect the housing for debris. Clean as needed.
- Note the orientation of the old filter and install the new one with the airflow arrows pointing in the same direction as indicated on the filter packaging.
- Reattach the housing cover securely. Return the glove box to its closed position and ensure it operates smoothly.
- Test the HVAC system by turning on the vehicle and running the fan to confirm air is flowing through the new filter properly.
Replacing the cabin filter regularly helps reduce interior odors and improve airflow through the HVAC system.
Maintenance tips and reminders
Typical replacement intervals can vary by driving conditions and vehicle use. As a general guideline for a 2023 Honda Pilot, consider:
- Engine air filter: about every 30,000 miles under normal driving; more frequently (e.g., 15,000–20,000 miles) in dusty or heavy-use environments. Always consult the owner’s manual for the exact interval.
- Cabin air filter: about every 15,000 miles or 12 months, whichever comes first. In dusty or urban environments, inspect and replace more often.
Always use the correct part numbers for your trim and climate. If you’re unsure, consult your owner’s manual or a trusted parts retailer, and consider having a technician verify the fitment.
Summary
Replacing the engine air filter and cabin air filter on a 2023 Honda Pilot is a straightforward, do-it-yourself maintenance task that can be completed in under an hour. Start with the engine air filter in the engine bay, ensuring the new filter is oriented correctly, then move to the cabin filter behind the glove box, again paying attention to orientation. Keep in mind recommended maintenance intervals and driving conditions to determine when to replace each filter. Regular replacement helps maintain engine performance, fuel efficiency, and interior air quality.
