Wehrli 06-07 GMC/Chevrolet 6.6L Duramax Stage 1 High Flow Intake Bundle Kit - Gloss Black

The OEM Y-bridge for these trucks is a poorly designed, slip-fit style two piece bridge with very little support and is prone to blowing apart under boost on hard working and high performance trucks creating poor drivability, reduced fuel economy, and decreased power. This kit is a much improved, high flow, bolt together style two piece 3" bridge which provides a secure sealing surface where the air inlet horn connects to the bridge. 3" high flow upper and lower intercooler pipes feature smooth flowing mandrel bends, CNC machined billet flanges and perfectly compliment the y-bridge to offer a full 3" tract from intercooler pipe slip connection to the engine incorporating the factory grid heater and EGR connection controls. The Driver (Hot) Side 3" Intercooler Pipe replaces the 2 1/2" OEM piece with a full 3" pipe. The stock part uses a reverse style bead roll design at the turbo which is prone to blowing off of the turbo under higher boost levels than stock. The 3.5" High Flow Passenger (Cold) Side Intercooler Pipe replaces the aging and failure prone factory plastic piece with a larger and more durable, high flow, 14 ga. aluminum fabricated 3.5" components. This part uses CNC machined flanges with double o-ring seals, comes supplied with new wire clip rings for both slip flanges, and uses an upgraded silicone hump boot with stainless steel t-bolt clamps to withstand higher boost pressures than stock to increase reliability and eliminate blown factory boots and horsepower robbing boost leaks. Finished in your choice of custom powder colors. Pairs best with emissions compliant tuning and drop in turbochargers for optimum performance gains.
