Wehrli Custom Fabrication WCF100409-DG Stage High Flow Intake Bundle Kit LML Duramax - 1

The Wehrli Custom Fabrication Stage 1 High Flow Intake Bundle Kit is engineered to maximize airflow between the turbo and engine on 2011-2016 LML Duramax applications. This comprehensive upgrade delivers improved throttle response, enhanced turbo spool-up, and increased efficiency by eliminating restrictive factory components and weak points prone to boost leaks.

Key Features:

• 3-inch high flow upper intercooler crossover pipe with 18% airflow gain over stock
• 3.5-inch passenger side (cold) intercooler pipe with 23% airflow gain over stock
• 3-inch driver side (hot) intercooler pipe for complete intake tract upgrade
• 14-gauge aluminum construction for durability in high-performance applications
• Premium silicone boots and T-bolt clamps to withstand higher boost pressures
• Threaded bung for reinstalling OEM intake temperature sensor
• Includes billet aluminum turbo resonator delete plate for OEM intake horn
• Compatible with OEM Y-bridge and connects to factory throttle valve and grid heater
• Custom powder coat finish in Dark Grey
• Made in USA

This bolt-on kit requires no tuning and fits stock trucks without additional modifications. The larger diameter pipes and smoother bends reduce airflow restrictions while eliminating the fragile factory boots that fail under high boost conditions, making this an ideal upgrade for towing, performance, and reliability.
