Wehrli 20-24 Chevrolet 6.6L L5P Duramax 4in Intake Kit - Bengal Blue

The Wehrli Custom Fab WCF100702-BB 4" Cold Air Intake Kit with Air Box is designed to replace the restrictive plastic factory components in 2020-2026 L5P 6.6L Duramax equipped Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks. This upgrade significantly improves engine performance by increasing airflow to the turbo, resulting in enhanced horsepower and torque, quicker throttle response, and cooler intake temperatures.

The system features an all-aluminum construction with a high-flow fabricated intake pipe and a custom-built air box enclosure, ensuring durability and optimal air velocity. The large-diameter 4" piping with smooth aerodynamic bends maximizes air volume, contributing to a more aggressive engine and turbo sound. It draws in cold air efficiently from both the hood Ram Air duct and the inner fender.

Installation is straightforward with basic hand tools, and no additional tuning or modifications are required for stock trucks. The kit includes all necessary components such as silicone boots, stainless steel T-bolt clamps, and a seal for the hood duct connection. It is available in various WCFab signature custom powder coat colors to match individual preferences.
