Designed to provide more horsepower and better acceleration for your truck or SUV, these Spectre kits replace factory air filters and intake housings, alleviating intake restriction as they smooth and straighten airflow. The high-flow design enables an engine to "inhale" a larger volume of air than an OEM filter assembly--more air means more usable power throughout the engine's RPM range. All Intakes Kits are C.A.R.B. approved or pending approval.
