Introducing the GMC Sierra 3500 HD Performance Air Intake by Wehrli, featuring a 4-inch WCFab design in a stunning Sparkle Copper finish for the `20-`25 models. This high-performance air intake system is engineered to replace the factory parts in your Chevrolet Silverado and GMC Sierra 2500 / 3500 HD trucks equipped with the L5P 6.6L Duramax engine, delivering an optimal increase in engine performance and efficiency.

The Wehrli 4-inch Performance Air Intake system is constructed from high-quality, fabricated aluminum, offering an increase in air flow to the turbo for improved horsepower, torque, and throttle response. Designed for efficiency, it draws cooler air through the hood's Ram Air duct and inner fender, greatly reducing intake temperatures. The system features smooth, aerodynamic bends that enhance intake air velocity and volume while providing a more robust engine and turbo sound during acceleration. The Sparkle Copper finish adds a unique touch, ensuring that your truck stands out as much in style as it does in performance.
