Intake Kit Stage 2 4in. for 2011-2016 Duramax LML Gun Metal

The WCFab 2011-2016 GM LML 6.6L Duramax 4" Intake Kit with Air Box Stage 2 is a high-flow, fabricated aluminum intake pipe and air box enclosure with a dry filter assembly. It replaces restrictive plastic factory parts for improved engine performance, increased airflow, horsepower, 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 more aggressive engine and turbo sound during acceleration. High-quality hardware, silicone boots, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation. Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover to help keep your MAF sensor, turbo, and engine airways contaminant free. Includes High Flow 4.8 in. Cast Aluminum Turbo Intake Horn removes restrictions in the OEM setup to improve turbo spool and top-end power and eliminates factory resonators for improved appearance and more aggressive turbo sound. This High Flow 4.8 in. horn is fully compatible with OEM and upgraded drop-in VGT style turbochargers. Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck. Not compatible with aftermarket LML Y-bridges that change the manifold/bridge inlet from the original factory (driver side inlet) location. NOTE: 2011 MODEL YEAR TRUCKS MUST UPDATE PCV Regulating Valve to 2012-2016 model year spec to allow correct fitment and compatibility with this part.
