The Wehrli Stage 2 intake kit for 2011–2016 Duramax LML 6.6L replaces restrictive plastic intake parts with a fabricated aluminum 4" intake and air box with dry filter, improving airflow to the turbo for better throttle response and cooler intake temps. Includes a 4.8" cast aluminum turbo intake horn compatible with OEM and drop-in VGT turbos. Bolt-on installation; 2011 trucks require a PCV valve update for fitment.
