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.
The part number for this item is Roush 401903 and it fits 2003-2007 Ford F-250 F-350 (6.0 Diesel Models).
