Upgrade your 2020-2025 Chevrolet Silverado 2500 HD, Silverado 3500 HD, or GMC Sierra 2500 HD with Wehrli's 4-inch high flow fabricated aluminum intake kit. This complete assembly replaces the factory plastic intake components, offering increased airflow to the turbocharger for improved horsepower and torque. The kit features a durable aluminum construction with large diameter smooth bends that enhance intake air velocity and volume, resulting in quicker throttle response and a more aggressive turbo sound during acceleration. The cold air intake design draws cooler ambient air through the hood Ram Air duct and inner fender, reducing intake temperatures and optimizing engine performance.
The installation process is straightforward, requiring only basic hand tools, and no tuning is necessary—simply bolt on the kit for immediate gains. The full assembly includes a high-quality dry filter, stainless steel T-bolt clamps, and a custom powder coat finish in gloss black for a sleek, custom look that complements your truck's aesthetics. The kit also features a seal for connection to the functional Ram Air port on the hood and an outerwear pre-filter cover for added filter protection. This upgrade is compatible with stock trucks without additional modifications or upgrades and replaces specific GM part numbers for a seamless fit.
Please note, failure to disable the air filter monitor system may result in a service message requiring dealer reset. The kit is EPA compliant and built with high-quality materials, including 10-gauge aluminum for the air box and lid, and a high-quality silicone boot for secure connections. This intake upgrade is designed to enhance your vehicle's performance while maintaining compatibility with factory components, providing a reliable and efficient solution for your Duramax-powered truck.
