GMC Sierra 2500 Performance Air Intake - Wehrli - Stage 2 - Candy Red - `20-`24 is a high-flow intake kit designed for 2020-2024 L5P 6.6L Duramax trucks. This bolt-on Stage 2 system replaces restrictive factory plastic components with fabricated aluminum for improved airflow and throttle response.

The Wehrli Stage 2 intake uses a 4" diameter aluminum pipe and an oversized intake horn to reduce restriction ahead of the turbo, drawing cold air through the hood Ram Air duct and inner fender. The full air box and lid are formed from 10-gauge aluminum and finished in Wehrli’s custom Candy Red powder coat. A dry filter with Outerwears pre-filter cover, high-quality silicone boot, and stainless steel T-bolt clamps are included for a complete, vehicle-ready assembly. No tuning is required for stock trucks, and the kit is made in the USA.
