This is a replacement filter for the Subaru SPT High Flow Air Intake system. This is the same filter that originally came with the intake.
The SPT Heat shield is designed for use with the SPT High Flow Air Intake. Its job is to shield the intake from radiant heat in the engine bay keeping your intake temperatures cold and allowing for better performance from your intake.
The SPT High Flow Air Intake is constructed of 319 diecast aluminum, manufactured to ensure the smoothest high flowing bends. Each system includes a silicone-reinforced boot, anti-vibration mounting system, stainless steel t-bolt clamps, and a SPT 4-layer cotton gauze filter with a built in velocity stack for smooth air flow.
