Wehrli 01-04 Duramax LB7 4in Intake Kit w/ Air Box Stage 2 - Sparkle Granny Smith

Elevate your 2001-2004 GM Duramax LB7 with Wehrli's Stage 2 Performance Air Intake. This high-quality aftermarket upgrade provides increased airflow to your engine, ultimately enhancing horsepower and torque. It includes a fabricated aluminum intake pipe and air box enclosure, which replaces the restrictive factory-installed plastic components. The system draws cooler air through the inner fender, leading to quicker throttle response and cooler intake temperatures. The smooth aerodynamic bends of the 4" piping facilitate enhanced air velocity and volume, producing a more aggressive engine and turbo sound during acceleration.
