Universal Replacement Air Intake Filter by Injen®. This filter will replace your worn-out performance filter. Built with surgical cotton gauze, the Injen filter elements are specifically built for chosen applications based on dimensions, pleat and flow rate. This is highly crucial to provide your engine with optimal performance gains. The built in velocity stack speeds up the airflow and removes the turbulence.

Note: This is the same oiled filter that came with your SP1899 intake.
