This high flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on your diesel for improved engine performance. All new design significantly increases air flow to your 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 more aggressive engine and turbo sound during acceleration. High quality hardware, silicone boot, 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 which removes restrictions in the OEM setup to improve turbo spool and top end power and eliminates factory resonator for improved appearance and more aggresive 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.
