GMC Sierra 2500HD Performance Air Intake - Wehrli - 4in with Air Box - Kiwi Green (2011–2016). A high-flow fabricated aluminum intake for the 6.6L Duramax LML that replaces restrictive factory parts.

Built by WCFab, this system uses a 4-inch mandrel-bent tube and an enclosed air box that pulls cool air from the inner fender to help lower inlet temps and improve response. A dry filter with a hydrophobic pre-filter helps keep the MAF, turbo, and intake tract clean. Quality silicone boot, seals, and stainless T-bolt clamps add durability, and the bolt-on design installs with basic hand tools. The removable lid simplifies inspection and maintenance. Finished in Kiwi Green powder coat and made in the USA.
