Chevrolet Silverado 3500 HD Performance Air Intake – Wehrli WCF 4in, Kiwi Green (2020–2025). This high-flow fabricated aluminum intake and air box replace restrictive factory parts on L5P 6.6L Duramax trucks.

Built around a 4-inch pipe with smooth bends and an aluminum air box enclosure, this kit pulls cool air from the hood Ram Air duct and inner fender to help lower intake temps, sharpen throttle response, and add a crisper turbo note. It bolts on with basic tools, needs no tuning, and is compatible with stock trucks. The durable Kiwi Green powder coat provides a tough, custom look under the hood.
