Add a new intake to your GM 6.6L Duramax today with the Wehrli Custom Fab WCF100194-GW 4" Intake Kit W/Air Box - Gloss White from GAP. 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. The design significantly increases airflow 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. The removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with an included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant-free.
