GMC Sierra 2500 HD Performance Air Intake by Wehrli (WCFab) — 4in Intake Kit in Sparkle Bomber Orange. Designed for 2020–2025 GMC Sierra 2500 HD with the 6.6L Duramax L5P, it replaces restrictive factory plastic parts with a high-flow aluminum system.

This kit combines a fabricated 10-gauge aluminum air box and lid with a large 4in intake tube using smooth bends to increase airflow to the turbo for improved throttle response and power feel. It draws cool air from the functional hood Ram Air duct and inner fender to help lower intake temps, while delivering a more assertive induction and turbo sound under load. The dry filter is easy to service, and the high-quality silicone boot with stainless T-bolt clamps provides a reliable connection. Direct bolt-on; no tuning required; compatible with otherwise stock trucks. After installation, disable the factory air filter life monitor to avoid service messages.
