Product details
WCFab 4" Intake Kit with Air Box for 2013-2018 6.7L Cummins equipped Ram 2500 / 3500 truck with OEM / factory style turbocharger. - - 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 and ram air duct in the grille. 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. Air box provides mounting provision for the OEM air box actuator so that it can remain plugged in for CEL free operation, but keeps both grille and fender ports fully open for maximum air flow to your turbo. - - Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.
