Intake Kit Stage 2 4in. for 2006-2007 Duramax LBZ Illusion Blueberry

This high-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts for improved engine performance. It increases airflow, horsepower, torque, provides quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. Features large diameter 4" piping with smooth aerodynamic bends. Includes high quality hardware, silicone boot, seals, and stainless steel t-bolt clamps. The removable air box lid allows for easy visual inspection and maintenance of the WCFab filter with an included hydrophobic pre-filter cover. Also includes a High Flow 4.8 inch Cast Aluminum Turbo Intake Horn, which removes restrictions in the OEM setup to improve turbo spool and top-end power and eliminates the factory resonator. The turbo horn is compatible with OEM and upgraded drop-in VGT style turbochargers. Available in custom powder coat colors (Illusion Blueberry for this MPN).
