Genuine Honda Passport Air Filter

For an engine to run smoothly, it needs a correct ratio of gasoline and air, so an air filter is a key component in maintaining automotive performance. They prevent abrasive particulate matter from entering the engine's cylinders, which can cause oil contamination and mechanical breakdown. Honda air filters need regular replacement, as a clogged filter can introduce allergens into the interior cabin air stream. Honda recommends changing them every 10,000 miles.
