Chevrolet Silverado 2500 HD Performance Air Intake – Wehrli Stage 2, 4 in., Kiwi Green (2020–2025). A high-flow fabricated aluminum intake and air box that replace restrictive factory plastic for sharper response and a deeper turbo note.

Built for the 6.6L Duramax L5P, this system boosts airflow to the turbo for improved power potential, quicker throttle response, and cooler intake temps by drawing fresh air from the hood Ram Air duct and inner fender. A full 4 in. intake pipe with smooth bends and an intake horn over an inch larger than OEM clear the pre‑turbo restriction. The 10‑gauge aluminum air box seals to the functional hood port, and the dry filter with Outerwears pre‑filter is easy to service. No tuning required; bolt‑on. Disable the factory air‑filter monitor to prevent a service message. Custom Kiwi Green powder coat. Made in the USA.
