The WCFAB 4" intake kit with airbox is a complete drop in replacement for the factory intake setup. This kit was designed to improve overall airflow and efficiency by removing the restrictive plastic pieces resulting in increased throttle response and overall performance.
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 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 hood Ram Air duct and inner fender. All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity and 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 included hydrophobic pre-filter cover to help keep your MAF sensor, turbo, and engine airways contaminant free. The critical ram air duct seal has been moved to the bottom of the hood for a clean engine compartment appearance. Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.
Each kit is sold complete with a dry intake filter, airbox, piping and all boots/clamps necessary for installation on the 2017-2019 L5P GM Duramax.
