About this product
Description
Wehrli's Stage 1 airflow bundle for the 2011-2016 LML Duramax: both intercooler pipes, the upper crossover pipe and the high-flow cast Y-bridge in one kit. It replaces every restrictive or leak-prone piece between the turbo and the heads and bolts on with no tuning, so it works on a stock truck as well as a built one.
The 3" driver (hot) side pipe replaces the two-piece 2.5" factory pipe for an 18% flow gain, the one-piece 14-gauge aluminum 3.5" passenger (cold) side pipe replaces the plastic two-piece factory pipe for 23%, and the CNC-machined cast aluminum Y-bridge flows 33% better than stock. Everything connects to the factory throttle valve, grid heater, EGR and intake runners. Includes silicone boots, stainless T-bolt clamps and a billet resonator plate for the OEM intake horn, powder coated in your choice of colour.
