Detailed Description

The Wix 46831 engine air filter is engineered to help maintain intake cleanliness in Honda Accord and Acura TSX vehicles. Its enhanced cellulose-based synthetic media is treated with phenolic resin for added durability against moisture ingestion, while the panel format supports straightforward OE-style fitment in the factory air filter housing. Wix also uses 30% more media than OES filters, helping provide greater filtration surface area for routine service intervals.
