Product Information
Injen SP short ram intake with a 6061-T6 aluminum intake tube that gives the engine a smooth, uninterrupted airflow path in place of the restrictive factory intake tract. A fully serviceable SuperNano-Web dry filter with increased surface area needs no oil. A custom heat shield separates the filter from engine bay heat. MegaRam (MR) and Air Fusion tuning keeps air/fuel ratios in range on the stock calibration, so no tune is needed. Dyno testing shows gains of up to 14 hp and 13 lb-ft, and the tube has a polished finish.
