The GMC Sierra Performance Air Intake - Wehrli - Stage 2, 4in. in Kiwi Green is an exceptional upgrade for your 2001 to 2004 Duramax LB7. This air intake kit is designed to replace your factory-installed restrictive plastic components, enhancing engine performance with improved airflow, horsepower, and torque.

Manufactured from high-quality aluminum, this performance air intake features large 4-inch diameter piping, expertly crafted with aerodynamic bends to boost air velocity and volume. By directing cold air through the inner fender, it reduces intake temperatures, facilitating a quicker throttle response and a more robust engine and turbo sound during acceleration. The removable air box lid allows for easy inspection and maintenance of your filter, while the included hydrophobic pre-filter cover ensures protection against contaminants.
