Chevrolet Silverado 3500 Performance Air Intake – Wehrli Stage 2, 4in, Chevy Orange (2020–2025). This high-flow fabricated aluminum intake and air box replaces restrictive factory plastics on L5P 6.6L Duramax trucks.

Designed to increase airflow to the turbo for improved horsepower and torque, quicker throttle response, and cooler intake temps, it draws cold air from the hood ram duct and inner fender. The large 4in piping with smooth bends boosts air velocity and produces a more aggressive engine and turbo sound under load. A 4in intake horn, over an inch larger than OEM, removes the stock bottleneck at the turbo inlet. No tuning required; bolt-on and compatible with stock trucks. Finished in Chevy Orange powder coat. Note: disable the factory air filter monitor to prevent a service message.
