The Chevrolet Duramax Performance Air Intake by Wehrli, Stage 2, Cat Yellow, is designed to transform your 2001-2004 GM LB7 6.6L Duramax engine. This advanced intake system enhances performance, replacing the factory's restrictive plastic parts with a high-flow, fabricated aluminum setup.

Crafted for superior engine performance, this intake system significantly boosts airflow, heightening turbo efficiency for improved horsepower and torque. The system draws cold air through the inner fender, leading to quicker throttle response and cooler intake temperatures. The all-aluminum construction features large diameter 4" piping with smooth bends, enhancing air velocity and volume while providing a more aggressive engine sound during acceleration. High-quality hardware, silicone boot, seals, and stainless steel T-bolt clamps guarantee durability and straightforward installation. The air box enclosure includes a removable lid for easy maintenance, ensuring your MAF sensor, turbo, and engine remain contaminant free.
