The Wehrli Stage 2 Intake Kit for 2011–2016 Chevrolet 6.6L Duramax LML replaces restrictive factory plastic intake parts with a high-flow fabricated aluminum pipe, air box and dry filter assembly to increase airflow to the turbo. It includes a 4.8-inch cast aluminum turbo intake horn, silicone boots, stainless t-bolt clamps, a removable air box lid with pre-filter cover, and installs bolt-on without tuning; 2011 trucks require a PCV valve update for fitment.
