  • This is the GrimmSpeed Stealthbox Cold Air Intake System designed to improve the performance of your vehicle! This system is a direct replacement for your factory restrictive intake and features a smooth intake tubefabricated from quality aluminum materials that maximizes air flow and limits air turbulence under boost. The result is improved throttle response with more horsepower, more torque, and an aggressive cold air intake noise under acceleration.

    Also included in the GrimmSpeed Stealthbox is a heat shield designed to keep those hot engine temperatures away from the filter so that the filter breathes in as close to ambient temperatures as possible. Both the heatshield and the intake tube will come powder-coated a nice red finish to provide a clean look to the engine bay and to have extra protection against rust and corrosion. 

    The GrimmSpeed Stealthbox will also come with weather stripping, high-temp silicone hose, and hardware to make this part ready for installation.
