Upgrade your 2020-2025 Chevrolet Silverado 2500/3500 HD or GMC Sierra 2500/3500 HD with the Wehrli Stage 2 Intake Kit, designed specifically for the Duramax L5P 6.6L engine. This high flow, fabricated aluminum intake system replaces the restrictive factory parts, resulting in improved airflow, increased horsepower and torque, and quicker throttle response. The kit features large diameter 4-inch piping with smooth aerodynamic bends that enhance intake air velocity and volume, while the over an inch larger intake horn reduces restrictions before the turbo inlet for maximum airflow efficiency. The design incorporates a dry filter assembly and a functional Ram Air duct and inner fender seal to draw cooler, denser air from outside the engine bay, helping to lower intake temperatures and boost engine performance.
