2011-2016 Duramax High Flow Turbo Intake Horn, Flat Black (WCF100417-FB)

4.8" cast aluminum turbo intake horn for the 2011-2016 LML Duramax, the largest inlet on the market for this truck. It replaces the restrictive plastic factory inlet and deletes the resonator, so the turbo gets more air, throttle response improves, and the truck sounds like it has a turbo. Built to go with Wehrli's Stage 1 LML intake and bundle kits.

Includes a PCV port, silicone reducer boot, stainless T-bolt clamps, O-ring seal and new EGR gaskets, powder coated in your choice of colour. Replaces GM 12642296 and 12637801. On 2011 trucks the PCV regulating valve must be updated to the 2012-2016 spec.
