The Injen RD Series cold air intake for 2002–2007 Subaru Impreza WRX and 2004 STI replaces stock intake plumbing with mandrel-bent 6061-T6 tubing and a SuperNano-Web dry filter to promote cooler, denser airflow and improved mid-range power. Dyno-proven gains are reported, and the kit maintains safe air/fuel ratios without extra tuning. Offered in polished or black with a limited lifetime warranty.
