Chevrolet Silverado 3500 Performance Air Intake - Wehrli - Stage 2 - Candy Red - `20-`24. A bolt-on Stage 2 intake for 2020–2024 L5P 6.6L Duramax Silverado/Sierra HD trucks that replaces restrictive factory plastic parts with a fabricated aluminum 4" intake, dry filter, and powder-coated airbox for improved airflow and engine response.

This Wehrli Stage 2 system uses high-flow, fabricated aluminum piping and a larger intake horn to reduce restriction ahead of the turbo. The design draws cooler air from the hood ram-air duct and inner fender, increases intake volume and velocity with smooth 4" bends, and contributes to a more aggressive engine and turbo note during acceleration. The airbox and lid are constructed from 10-gauge aluminum and finished in Wehrli's custom Candy Red powder coat. Hardware includes quality silicone boots and stainless steel T-bolt clamps; an Outerwears pre-filter cover is included. No tuning is required for stock trucks — this is a direct bolt-on replacement for the listed GM part numbers.
