Wehrli Custom Fab Stage 3 High Flow Bundle Kit for 2007.5–2010 Duramax LMM replaces restrictive factory intake and intercooler plumbing to increase airflow to the turbo for improved horsepower, torque, and cooler intake temps. The all-aluminum 4" piping, massive 4.8" intake horn, CNC flanges with double O-rings, and upgraded silicone boots reduce boost leaks. A 3" stainless downpipe and heavy-duty 3"/3.5" intercooler pipes complete the bolt-on kit with removable airbox lid and hydrophobic pre-filter.
