Product Description
The WEHRLI CUSTOM FAB WCF100367 3.5" PASSENGER SIDE INTERCOOLER PIPE KIT is engineered to eliminate airflow restrictions and weak factory piping on the 2006-2010 LBZ and LMM Duramax. The factory intercooler pipe on these trucks can become a restriction point under higher boost levels, especially on tuned or modified trucks. Wehrli Custom Fabrication developed this high-flow replacement to improve airflow efficiency, durability, and boost response.
Constructed from precision mandrel-bent aluminum tubing with a larger 3.5-inch diameter, this passenger side intercooler pipe dramatically improves airflow between the intercooler and intake system. The kit includes high-quality silicone boots and heavy-duty clamps to ensure a leak-free connection under high boost pressure. Whether you're building a towing truck or a high-horsepower Duramax setup, this upgrade provides improved airflow reliability and performance.

Frequently Asked Questions
What does the passenger side intercooler pipe do?
The passenger side pipe carries compressed air from the intercooler to the intake system. Upgrading to a larger diameter pipe improves airflow and helps maintain boost pressure under load.
Why upgrade the factory intercooler pipe?
The factory pipe can become restrictive and prone to failure under higher boost levels. This Wehrli upgrade provides stronger aluminum construction and increased airflow capacity.
Will this work with a stock turbo?
Yes. This kit is compatible with stock turbochargers as well as upgraded turbo systems on LBZ and LMM Duramax engines.
Is tuning required for installation?
No tuning is required. This is a bolt-on airflow upgrade that works with factory or modified engine calibrations.
Does the kit include boots and clamps?
Yes. The kit includes heavy-duty silicone boots and stainless T-bolt clamps to ensure secure connections and boost leak prevention.
