Chevrolet Silverado 3500 HD Performance Air Intake — Wehrli 4in Intake Kit, Bengal Grey (2020–2025). High-flow aluminum intake and air box replacing restrictive factory parts for better breathing.

Built for the 6.6L Duramax L5P, this bolt-on kit uses a 4 in aluminum tube and a 10‑gauge air box with a dry filter to move more air to the turbo. Expect crisper throttle response, cooler intake temps via the hood Ram Air duct and inner fender, and a stronger engine/turbo note. Installs with basic tools; no tuning required; fits stock trucks—no other mods needed. After install, disable the OE air filter monitor to avoid a service message.
