Injen RD Series Polished Cold Air Intake for 2002-2007 Subaru Impreza WRX & STI (RD1200P)

Fits 2002-2007 Subaru Impreza WRX and WRX STI models (Excludes Wagon).

The Injen RD Series Cold Air Intake is engineered to deliver significant performance gains for the GD-chassis Subaru Impreza. By positioning the air filter deep within the engine bay to draw in cooler, denser air, this system optimizes combustion efficiency for increased horsepower and torque. The intake features a mandrel-bent 6061-T6 aluminum tube that maintains consistent diameters through every bend, eliminating the airflow restrictions and turbulence found in factory induction systems.

Equipped with Injen’s SuperNano-Web dry air filter, this kit provides high-level filtration without the need for filter oil. The RD1200P is designed to maintain safe air-to-fuel ratios, ensuring performance gains of up to 24.4 HP and 24 lb-ft of torque without requiring an immediate ECU tune. Proudly manufactured in Pomona, California, this intake system is CARB-exempt under EO #D-476-5, making it street-legal in most jurisdictions.
