The K&N Universal air filter is a universal replacement specified with a 2½-inch flange, 3½-inch outer diameter and 6-inch overall height. These measurements allow you to confirm compatibility with custom intake assemblies or aftermarket housings where precise flange size and overall height determine fit. Check the listed dimensions against your intake before purchasing.
