High Flow Bundle Kit Stage 1 2007.5-2010 Duramax LMM Candy Purple

The Wehrli Stage 1 High Flow Intake replaces the restrictive OEM Y-bridge with a high-flow, bolt-together 3" bridge. It includes 3" high-flow upper and lower intercooler pipes with mandrel bends and CNC machined billet flanges, providing a full 3" tract from intercooler pipe slip connection to the engine. The kit incorporates factory throttle valve, grid heater, and EGR controls. The Driver (Hot) Side 3" Intercooler Pipe replaces the 2 1/2" OEM piece with a full 3" pipe. The 3.5" High Flow Passenger (Cold) Side Intercooler Pipe replaces the factory plastic piece with a larger, more durable, 14 ga. aluminum fabricated 3.5" component. It features CNC machined flanges with double o-ring seals, new wire clip rings, and an upgraded silicone hump boot with stainless steel t-bolt clamps for higher boost pressures. This intake is available in custom powder colors and is best paired with emissions-compliant tuning and upgraded drop-in turbochargers.
