Wehrli WCFab 4in Intake Kit with Air Box for 2017-2019 Chevrolet/GMC 2500HD/3500HD (6.6L L5P) - Gloss Black WCF100344-GB

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD (6.6L L5P Duramax).

The Wehrli Custom Fabrication (WCFab) 4-inch Intake Kit replaces the restrictive plastic factory components on your diesel with high-flow, fabricated aluminum parts. This kit significantly increases air volume to the turbocharger, improving throttle response and maintaining cooler intake temperatures by drawing air from both the functional hood ram air duct and the inner fender. The large 4-inch piping features smooth aerodynamic bends to maximize air velocity while providing a more aggressive engine and turbo sound during acceleration.

This kit is a true bolt-on solution that requires no additional tuning or modifications. It includes a removable air box lid for easy maintenance and an Outerwear’s hydrophobic pre-filter to protect your MAF sensor and engine airways from contaminants. The entire assembly is finished in a durable Gloss Black powder coat (MPN: WCF100344-GB) for a professional look under the hood.
