The Injen SP short-ram intake for MazdaSpeed3 (2007–2013) replaces restrictive factory plumbing with a smooth 6061‑T6 aluminum intake tube and incorporates Injen’s MR tuning features. The kit includes a serviceable SuperNano‑Web dry air filter, custom heat shield, tubing, hardware and instructions. Dyno-proven gains of about +7 HP and +9 lb‑ft, an aggressive intake tone, multiple finishes and Injen’s limited lifetime warranty are supported.
