K&N Custom Air Filter Kits are designed to boost the performance of your carburetor while providing superior filtration to keep dirt on the outside where it belongs. This assembly comes with a carbon fiber look top and blank base plate as well as a K&N high-flow air filter designed to increase horsepower and acceleration. The base does not have any holes cut through, so it can be made to fit almost any stack configuration. Once the base has been put in place, simply slip the main filter assembly over the stacks. This custom air filter kit can fit single or two barrel carburetors. Supplied spring clip clamps keep the filter securely together for a positive seal and ease of servicing.
