• SPECIFICATIONS: Conical-shaped axial seal air filter element with inside-out flow direction. O.D.: 7-13/32 in. (188.1 mm) to 10-13/32 in. (264.3 mm) | I.D.: 6-15/16 in. (176.2 mm) one end | Length: 29 in. (736.6 mm) | Includes: Two (2) attached gaskets (G298-AF) for a secure, leak-free seal against the air cleaner housing.
• HEAVY-DUTY AXIAL SEAL DESIGN: Rigid metal end caps with compressed attached gaskets form a positive axial seal against the housing — preventing air bypass and ensuring 100% of intake air passes through the filter media. The conical shape maximizes media surface area within the air cleaner housing for increased dust-holding capacity and extended service intervals under demanding on-highway and vocational duty cycles.
