The K&N air filter vent kit elbow adapter is a universal vent fitting intended for smog tubes, crankcase and valve cover vents. Offered in a 90-degree plastic elbow with a 0.50in flange, it requires drilling a hole in the air filter base or valve cover for installation. Each kit ships with the necessary mounting hardware and gasket, and K&N provides straight and elbow configurations across a range of sizes for common venting setups.
