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

Classic Gloss Black and measured airflow gains across the board -- this Wehrli Stage 2 High Flow Intake Bundle Kit replaces every weak point in the 2007.5-2010 LMM Duramax intake tract. From restrictive plastic factory pieces to leak-prone rubber fittings, it all gets swapped for properly sized aluminum and reinforced silicone at a bundle price that saves over $196.

Intake System

Starting at the front, a 4 in. aluminum intake pipe with enclosed air box pulls cold air through the inner fender for lower intake temperatures. The dry filter and Outerwears hydrophobic pre-filter cover keep contaminants away from your MAF sensor and turbo. The 4.8 in. turbo intake horn -- the largest for this application -- opens up airflow by 20% over stock and gives the turbo a deeper, more aggressive sound during acceleration. Every piece is 14 ga. aluminum with smooth mandrel bends.

Intercooler Piping and Y-Bridge

The factory 2.5 in. hot side intercooler pipe and plastic cold side pipe get replaced with Wehrli's one-piece 3 in. hot side and 3.5 in. cold side aluminum pipes. That cold side improvement alone? 47% better airflow than factory. CNC machined flanges with double O-ring seals and upgraded silicone boots handle higher boost pressures and put an end to the blown-boot failures that plague these trucks.

Wehrli's 3 in. two-piece Y-bridge ties it all together, replacing the factory slip-fit unit with a bolt-together design that flows 36% better and actually stays sealed under boost. CNC billet flanges, mandrel bends, and a full 3 in. tract from intercooler to engine. Factory grid heater and EGR connections remain intact. No tuning needed.
