The GMC Sierra 3500HD Performance Air Intake by Wehrli is a high flow cast aluminum intake horn designed for the 2011-2016 models. Powder coated in a striking Illusion Blueberry finish, this intake horn replaces the stock plastic inlet, enhancing airflow to the turbocharger for improved performance and throttle response.

Crafted to replace GM Part Numbers 12642296 and 12637801, this intake horn is designed to work seamlessly with your existing setup as long as it features a silicone boot connection. Note that for 2011 model year trucks, the PCV regulating valve must be updated to 2012-2016 specifications for compatibility. Its aluminum construction not only boosts durability but also eliminates the resonator for a more aggressive engine sound. This high performance component includes an O-ring seal, new EGR gaskets, and stainless steel T-bolt clamps, further ensuring improved performance and reliability.
