Injen Technology X-1018-BR Black and Red 4.5" High Performance Air Filter

A high performance intake isn’t high performance without the filter. Constructed of surgical cotton gauze, the Injen filter element comes precisely oiled to maintain consistent airflow and prevent obstructions to the intake system. Each filter is specifically chosen for every application, as the dimensions, pleat and flow rate are highly crucial to optimal performance gains. Each injen filter has a built in velocity stack that aids in speeding up and straightening airflow.
