Injen’s polished SP short‑ram intake for 2008–2012 Lexus IS‑F V8 swaps restrictive factory tubing for a 6061‑T6 aluminum runner, SuperNano‑Web dry filter and a vehicle‑specific heat shield to boost airflow. Dyno testing cites gains up to +26.2 HP and +36.5 ft‑lb torque while MR and Air Fusion technologies hold safe A/F ratios. The kit includes hardware and instructions, increases intake sound and is not CARB exempt.
