2006-2007 Duramax Stage 1 High Flow Bundle Kit, Gloss Black (WCF100323-GB)

Wehrli's Stage 1 airflow bundle for the 2006-2007 LBZ Duramax: the 3" two-piece Y-bridge with upper crossover and lower intercooler pipes, plus the 3" hot side and 3.5" cold side intercooler pipes. 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 bolt-together Y-bridge kit flows 36% better than the slip-fit factory bridge that blows apart under boost, and the 3.5" cold side pipe flows 47% better than stock. The hot side pipe uses a high-temperature wire-reinforced boot. Includes silicone boots, stainless T-bolt clamps, installation hardware and all required seals and gaskets, powder coated in your choice of colour.
