PRL Motorsports Stage 1 Intake System w/Filter and Intake HoseThe PRL Motorsports Stage 1 Intake System offers great gains at an affordable price. This kit replaces the corrugated factory inlet hose with our better looking, smoother flowing 4 ply silicone hose and high flow air filter. The pleats found in the factory hose disrupts air flow, which limits power potential and throttle response. Adds 6+ horsepower & 5 ft lb torque throughout the power band. Why use a PRL Motorsports air filter? Decades of experience
