Two: one engine air filter and one cabin air filter.
In practice, this two-filter setup is standard across most Honda Pilot generations, though exact replacement intervals may vary by year and driving conditions. This article explains what each filter does, where to find them, and how to maintain them.
The two air filters in a Honda Pilot
The Pilot typically uses two distinct air filters to keep air clean for both the engine and the passenger compartment.
Here are the two air filters and where to find them in a typical Honda Pilot.
- Engine air filter — located in the engine compartment inside a rectangular air filter housing. Access is gained by unclipping or unbolting the housing cover to replace the filter.
- Cabin air filter — located behind the glove box inside the cabin. Access usually requires removing the glove box panel or damper to replace the filter.
These two filters serve different purposes: the engine air filter cleans intake air for combustion, while the cabin air filter cleans air entering the interior through the HVAC system. The count remains two across most models, though some trims may use a more advanced cabin filtration setup inside the same two-filter framework.
Maintenance considerations
Replacement intervals depend on model year and driving conditions. In general, consult the owner's manual for exact recommendations, but typical guidance places engine air filter replacement around every 30,000 miles under normal use, and cabin air filter replacement around 15,000–25,000 miles, with more frequent checks in dusty or high-traffic environments.
Summary
For a Honda Pilot, the answer is straightforward: two air filters—one for the engine and one for the cabin. They are located under the hood and behind the glove box, respectively, and should be inspected and replaced according to the vehicle’s manual to maintain performance and air quality across model years.
