GMC Sierra HD Performance Air Intake - Wehrli - High Flow Cast Aluminum - Brizzle Blue - 2011-2016. This intake horn replaces the restrictive OEM plastic inlet to increase airflow and sharpen throttle response on Duramax LML trucks.

Built from cast aluminum with a 4.8 in inlet and a durable Brizzle Blue powder coat, it routes more air directly to the turbo. An integrated PCV port and resonator delete tidy the bay and bring out more turbo and engine sound. Designed to pair with WCFab Stage 1 LML intake kits. Requires an intake pipe that accepts a 4 in silicone boot and clamp; systems with molded rubber connections will not fit. 2011 trucks must update the PCV regulating valve to 2012-2016 spec. Not compatible with aftermarket LML Y-bridges that relocate the inlet. Replaces GM 12642296 and 12637801.
