Wehrli 2007.5-2010 Chevrolet Duramax 6.6L LMM Stage 2 High Flow Intake Bundle Kit - Chevy Orange

Nothing says Chevy quite like orange under the hood. This Wehrli Stage 2 High Flow Intake Bundle Kit in Chevy Orange replaces every restrictive factory intake component on your 2007.5-2010 LMM Duramax with properly sized aluminum -- all color-matched in a finish that pays tribute to the brand. Bundle pricing saves over $196 versus buying each piece separately.

Intake Assembly

A 4 in. aluminum intake pipe with enclosed air box and dry filter pulls cold air through the inner fender for lower intake temperatures. The included Outerwears hydrophobic pre-filter cover adds protection against moisture and debris. Wehrli's 4.8 in. turbo intake horn flows 20% better than the factory unit and adds a deeper turbo sound under acceleration. All piping is 14 ga. aluminum with smooth mandrel bends for minimal turbulence.

Intercooler Pipes

On the pressure side, the factory 2.5 in. hot side pipe and plastic/rubber cold side pipe get replaced with Wehrli's one-piece 3 in. hot side and 3.5 in. cold side aluminum pipes. The cold side achieves a 47% airflow improvement over stock. CNC machined flanges with double O-ring seals and upgraded silicone boots are built for higher boost pressures, eliminating the blown boots that commonly affect these trucks.

Y-Bridge

Completing the intake tract, Wehrli's 3 in. two-piece Y-bridge replaces the factory slip-fit design that tends to blow apart. The bolt-together construction flows 36% better than stock, with CNC billet flanges and mandrel bends maintaining a full 3 in. path from intercooler to engine. Factory grid heater and EGR connections stay put. No tuning needed -- bolts on to stock trucks.
