Injen’s SP short‑ram intake for 2008–2012 Lexus IS‑F V8 replaces restrictive stock plumbing with a smooth 6061‑T6 aluminum tube, SuperNano‑Web dry filter and a custom heat shield for this application. Dyno gains are substantial—up to +26.2 HP and +36.5 ft‑lb torque—while MR and Air Fusion tuning maintain safe A/F ratios. The system includes hardware and instructions, increases intake tone, and is not CARB exempt.
