The GMC Sierra Performance Air Intake by Wehrli – 4in Intake Kit + Air Box – Gloss Black – `01-`04 is a premium upgrade designed for the 2001-2004 Duramax LB7 engine. It's a complete air intake system that enhances your engine's performance by replacing restrictive factory components with high-quality fabricated aluminum parts.

Engineered for improved airflow and performance, the Wehrli Performance Air Intake Kit features a robust construction with large 4-inch diameter piping and smooth aerodynamic bends. This design increases air velocity and volume, resulting in better horsepower, torque, and throttle response. The enclosed air box and dry filter assembly keep intake temperatures cooler by drawing cold air through the inner fender, while protecting the engine components. High-quality hardware, a silicone boot, seals, and stainless steel T-bolt clamps ensure durability and ease of installation. No tuning is required, and it easily installs with basic hand tools.

Features
