GMC Sierra 2500 HD Performance Air Intake by Wehrli (WCFab) - 4in, Kiwi Green, 2020-2025. This bolt-on assembly replaces the restrictive factory intake with a high-flow aluminum system and dry filter for the 6.6L Duramax L5P.

Designed to draw cool air from the hood Ram Air duct and inner fender, it improves airflow to the turbo for quicker throttle response, stronger pull, and reduced intake temperatures. The 4 in smooth-bend aluminum tube and enclosed air box balance velocity and volume while adding a deeper turbo note. Durable Kiwi Green powder coat. Installs with basic tools; no tuning required; fits stock trucks. Disable the factory Air Filter Monitor to prevent a Service Air Filter message after install.
