GMC Sierra 3500 HD Performance Air Intake - Wehrli - Stage 2 - Bengal Blue (2020-2025). Fabricated aluminum intake and air box replace restrictive factory plastic to feed cooler, higher-volume air to L5P 6.6L Duramax trucks.

Drawing cold air from the functional hood Ram Air duct and inner fender, this kit increases airflow to the turbo for improved horsepower and torque, quicker throttle response, and a deeper turbo note. The 4-inch aluminum tubing with smooth bends aids velocity, and the enlarged intake horn removes the restriction just before the turbo inlet. It is a true bolt-on for stock trucks with no tuning required and comes finished in WCFab’s Bengal Blue single-stage powder coat.

• 4-inch aluminum intake pipe and enlarged intake horn
• 10-gauge aluminum air box and lid with Ram Air hood seal
