The Injen RD cold air intake for 1998–1999 Subaru Impreza installs mandrel-bent 6061-T6 aluminum tubing and a SuperNano-Web dry filter to improve airflow and mid-range power. The system places the intake behind the bumper to draw cooler air, helps maintain safe air/fuel ratios without additional tuning, and is offered polished with supporting CARB EO where specified and Injen’s limited lifetime warranty.
