Chevrolet Silverado 2500 HD Performance Air Intake by Wehrli — 4 in High Flow, Aluminum, Dry Filter, Sparkle Granny Smith (2020–2025). This bolt-on system replaces restrictive factory components to let your 6.6L Duramax L5P breathe better and respond quicker.

Fabricated from 10-gauge aluminum with a large 4 in intake tube and smooth bends, this kit draws cool air from the functional hood Ram Air duct and inner fender for improved airflow, throttle response, and intake temps. The enclosed air box, precision seal to the hood duct, and dry filter deliver reliable performance and a more assertive engine/turbo note under load. Finished in WCFab’s Sparkle Granny Smith powder coat. No tuning required; installs with basic hand tools on stock trucks.
