Intake Kit Stage 2 4in. for 2004.5-2005 Duramax LLY Bengal Silver

This high-flow, fabricated aluminum intake kit with a dry filter assembly replaces restrictive plastic factory components to significantly improve engine performance. It increases airflow, horsepower, torque, and quickens throttle response while drawing cold air from the inner fender for cooler intake temperatures. The kit features a large diameter 4" aluminum piping with smooth aerodynamic bends, a removable air box lid, and an included hydrophobic pre-filter cover. It also incorporates a High Flow 4.8" Cast Aluminum Turbo Intake Horn, compatible with both OEM and upgraded VGT turbos, designed to remove OEM restrictions and eliminate the factory resonator. The entire system is finished in a custom powder coat color and is manufactured in the USA.
