    Complete Bolt on ITB kit for Gen3 GM LS series V8 engines (cathedral port)

    This is a complete bolt on kit that will fit ALL LS series GM / Chevrolet engines with cathedral port heads.

    Maintains all standard equipment such as TPS, IAC, fuel rail and injectors. Also comes with high mounted fuel rail option to run secondary injectors or NOS etc.

    Our testing has shown this kit to produce peak gains of up to 45rwHp over the standard intake on a completely stock engine, with NO loss to mid range torque or power. With proper setup and tuning this drives just like an oem tuned vehicle with perfect driveability, starting and idle control.

    When coupled with a performance cam we have seen power exceed 400 wHp (300+ wKw) on otherwise stock 5.7L engine.

    Note this kit includes the pictured backing plate and FRP-carbon fiber airbox / scoop. See our other listing for kits with basic open trumpets if the scoop is not needed.
