Intake Kit Stage 2 4in. for 2007.5-2010 Duramax LMM Cherry Frost

The Wehrli Custom Fabrication 100303-CF is a 4-inch Stage 2 Cold Air Intake Kit with an Air Box and Intake Horn designed to replace restrictive plastic factory air intake components in 2007.5-2010 GM Silverado/Sierra 2500HD/3500HD trucks with the 6.6L Duramax LMM diesel engine. This high-flow, fabricated aluminum intake pipe and air box enclosure increases airflow to the turbo, leading to improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. The system also produces a more aggressive engine and turbo sound during acceleration. It features 14-gauge aluminum construction for the intake pipe and 10-gauge aluminum for the air box and lid. The kit includes a dry air filter, Outerwear's pre-filter cover, a 4.8-inch inlet aluminum intake horn, silicone reducer boot, stainless steel T-bolt clamps, O-ring seal, and all necessary installation hardware. It is compatible with OEM and drop-in VGT turbochargers and does not require tuning. The full assembly is available in various custom powder coat colors.
