Chevrolet Silverado 3500 HD Performance Air Intake - Wehrli - 4in Intake Kit - Fine Texture Black - '20-'25. A high-flow aluminum intake and enclosed air box engineered for the 6.6L Duramax L5P to replace restrictive factory components.

Fabricated 4 in intake tubing with smooth bends and a dry filter sits in a robust 10-gauge aluminum air box that seals to the functional hood Ram Air port, pulling cooler air from the hood duct and inner fender. Expect increased airflow to the turbo for improved throttle response, potential gains in horsepower and torque, lower intake temps, and a deeper induction and turbo sound. Finished in fine texture black powder coat, it installs with basic hand tools; it is a direct bolt-on for 2020–2025 Silverado 3500 HD with no tuning required and no other mods on stock trucks. For best results, disable the factory air filter monitor to avoid service messages.
