Chevrolet Duramax Performance Air Intake - Wehrli - 4in with Air Box - Bengal Red (2007.5–2010 LMM). Fabricated aluminum intake and air box replacing restrictive factory parts for better breathing and quicker response.

The WCFab 4-inch kit draws cooler air from the inner fender into a dry filter within a robust air box, then feeds your turbo through large, smooth-bend aluminum tubing. Expect improved airflow, crisper throttle response, and reduced intake temps. Premium silicone coupler, stainless T-bolt clamps, and a removable lid add durability and easy service. Bolt-on installation with basic hand tools; no tuning required. Finished in Bengal Red and made in the USA.
