The Injen SP short‑ram intake for 2012–2013 BMW 335i (N55, automatic transmission only) uses 6061‑T6 aluminum piping and Injen's patented MR and Air Fusion tuning to improve airflow while maintaining safe A/F ratios. The system includes a SuperNano‑Web dry filter and custom heat shield, delivers dyno‑proven gains (about +13 hp and +11 lb‑ft), produces an aggressive intake tone and is covered by Injen's limited lifetime warranty; not CARB‑exempt.
