The Injen RD cold air intake for 2000–2001 Subaru Impreza models replaces restrictive stock air paths with smooth mandrel-bent 6061-T6 aluminum tubing and a SuperNano-Web dry filter to improve mid-range power and throttle response. The one-piece design draws denser air from behind the bumper, preserves safe A/F ratios without extra tuning, and is available polished with a limited lifetime warranty.
