    Benefits of adding this mod

    A factory air intake system compromises your performance with restrictive tubing and low quality paper air filters. Upgrading to a wide breathing cold air intake optimized for delivering cooler, more dense air to your engine is the least expensive way to boost power and increase your fuel mileage. Take it a step further with our selection of forced induction turbos or superchargers to maximize your motor’s performance and breathe new life into your custom build.
