Description

WCFab 4" Intake Kit with Air Box for 2017-2019 GM L5P 6.6L Duramax equipped Chevrolet Silverado and GMC Sierra 2500 / 3500 HD trucks.

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.

-Installs easily with basic hand tools.

-NO Tuning required, bolt-on!

-Will fit on stock truck no other modifications or upgrades necessary!
