Intake Kit Stage 2 4in. for 2006-2007 Duramax LBZ Gloss Black

High-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly. Replaces restrictive plastic factory parts on diesel engines for improved performance. Significantly increases airflow to the turbo, producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. All-aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity, volume, and provide a more aggressive engine and turbo sound. Includes high-quality hardware, silicone boot, seals, stainless steel T-bolt clamps. Removable air box lid for easy inspection and maintenance of the WCFab filter with an included hydrophobic pre-filter cover. Includes a High Flow 4.8 in. 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. Compatible with OEM and upgraded drop-in VGT style turbochargers. No tuning required. Finished in WCFab's signature custom powder coat colors.
