2006-2010 LBZ/LMM Duramax High Flow Turbo Intake Horn

The biggest inlet Wehrli makes for the LBZ/LMM

Wehrli's CNC-machined cast aluminum horn replaces the restrictive plastic factory inlet on the LBZ/LMM. Wehrli rates it at about 20% more airflow, calls its 4.8 in. inlet the largest on the market, and says it improves performance and throttle response.

It has a PCV port and drops the factory resonator for a cleaner look and a stronger turbo and engine sound. It is designed to pair with Wehrli's Stage 1 LBZ/LMM intake kits.

Who it's for

LBZ/LMM owners with an intake that connects with a 4 in. boot and clamps.
