The Injen RD Series cold air intake for the 2002–2003 Toyota Matrix XRS is a bolt-on kit that replaces restrictive factory piping with mandrel-bent 6061‑T6 tubing and a SuperNano‑Web dry filter to improve airflow. Dyno-proven gains up to 14.2 hp are reported while maintaining safe A/F ratios; the system is available in polished or black finishes, produces a more aggressive intake tone and is backed by Injen Technology's limited lifetime warranty.
