Chevrolet Silverado 2500 HD Performance Air Intake - Wehrli - 4in WCFab - Gun Metal (2020–2025). High-flow fabricated aluminum intake and air box that replace restrictive factory plastic on L5P 6.6L Duramax trucks for better airflow and response.

Built around a 4 in. tube with smooth bends, it draws cool air through the hood Ram Air duct and inner fender to help lower intake temps while increasing volume. The 10-gauge aluminum air box and lid pair with a dry filter and included Outerwears pre-filter. Finished in Gun Metal powder coat, it installs with basic hand tools, needs no tuning, and works with stock trucks. Note: the air filter monitor may need to be disabled to prevent service messages.
