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

A stealthy Flat Black finish and serious airflow gains make this Wehrli Stage 2 High Flow Intake Bundle a solid choice for 2007.5-2010 LMM Duramax owners who want function without flash. Every restrictive factory intake component from filter to engine gets replaced with properly sized aluminum pieces, saving over $196 compared to buying individually.

Pre-Turbo Intake

The 4 in. aluminum intake pipe with enclosed air box and dry filter pulls cool air through the inner fender instead of recycling hot under-hood air. An Outerwears hydrophobic pre-filter cover keeps moisture and debris out while letting the filter breathe. The 4.8 in. turbo intake horn -- the largest for this application -- flows 20% better than stock and gives the turbo a noticeably deeper note under throttle.

Post-Turbo Piping

After the turbo, Wehrli swaps the factory 2.5 in. hot side pipe and the failure-prone plastic/rubber cold side pipe for a 3 in. one-piece hot side and 3.5 in. one-piece cold side, both in heavy 14 ga. aluminum with mandrel bends. The cold side pipe alone flows 47% better than the factory part. CNC machined flanges with double O-ring seals and upgraded silicone boots are built for higher boost pressures, so the blown-boot failures common on these trucks become a thing of the past.

Y-Bridge

Wehrli's signature 3 in. two-piece Y-bridge replaces the weak OEM slip-fit bridge with a bolt-together design that flows 36% better. CNC billet flanges and smooth mandrel bends create a full 3 in. air path to the engine while retaining factory grid heater and EGR connections. No tuning, no modifications -- just bolt on and go.
