Wehrli Custom Fab's Stage 2 intake kit for 2011–2016 Duramax LML replaces the factory intake plumbing with a high-flow aluminum pipe, air box and dry filter to increase turbo airflow and throttle response. Finished in WCFab grey, the kit includes a 4.8-inch cast turbo horn, silicone boots, stainless t-bolt clamps, O-rings and installation hardware, and is a bolt-on upgrade that requires a 2012-spec PCV update for 2011-model trucks.
