GMC Sierra 2500 HD Performance Air Intake - Wehrli - Stage 2 - Bengal Blue - 2020-2025. This high-flow intake and air box kit replaces restrictive factory parts to improve response, sound, and airflow on L5P 6.6L Duramax trucks.

Built from 10-gauge aluminum with a dry filter, the Stage 2 system uses a 4" intake pipe and matching 4" intake horn with smooth bends to increase air velocity and volume. It draws cool air through the functional hood Ram Air port and inner fender for quicker throttle response and a more pronounced turbo note. Finished in WCFab Bengal Blue powder coat, it’s a direct bolt-on for 2020-2025 Silverado/Sierra 2500/3500 HD L5P—compatible with stock trucks and no tuning required. Disable the factory air filter monitor in vehicle settings to prevent a service message; when set correctly, Air Filter Life will show Disabled. Replaces GM 84841229, 84841225, 84262962, 85614333, 84554702.
