Chevrolet Silverado 3500 HD Performance Air Intake - Wehrli - Stage 2, 4in. - Kiwi Green (2020-2025). This high-flow fabricated aluminum intake and air box replace restrictive factory plastic to deliver colder, cleaner airflow to your L5P 6.6L Duramax.

This bolt-on kit needs no tuning and uses a 4-inch intake pipe plus a matching 4-inch intake horn—over an inch larger than OEM—to cut restriction before the turbo. Smooth bends and a sealed link to the hood Ram Air duct pull cool air from the inner fender for improved power, quicker throttle response, cooler IATs, and a deeper turbo note. Finished in WCFab Kiwi Green and compatible with stock trucks. Note: disable the factory air filter monitor to avoid a service message.
