Roush Performance Cold Air Intakes are an easy and effective way to gain horsepower. By eliminating the restrictive factory intake tube and air filter and replacing them with a higher flowing intake tube and performance air filter, Roush Intakes allow cooler air to flow more freely into the engine, creating more power. You'll also notice a distinct growl at higher RPMs. Roush Intakes also are carefully engineered for each specific application, meaning you won't need to do any tuning. These are a true bolt on and drive modification. Roush Cold Air Intakes come with everything you need for an easy installation, including easy to follow instructions.
