Product Description
Improve airflow and eliminate restrictive factory piping with the WEHRLI CUSTOM FAB WCF100708 3" DRIVER SIDE (HOT SIDE) INTERCOOLER PIPE KIT designed specifically for the 2017-2019 L5P Duramax platform. Wehrli Custom Fabrication engineered this upgrade to replace the factory hot-side charge pipe with a high-flow 3-inch mandrel-bent aluminum intercooler pipe, dramatically improving boost flow and reliability under high load conditions.
The factory L5P intercooler piping can become a bottleneck when increasing boost levels through tuning or turbo upgrades. The Wehrli WCF100708 intercooler pipe kit increases internal diameter and smooths airflow transitions to reduce turbulence and pressure drop. Built with durable aluminum construction and reinforced silicone couplers, this kit ensures consistent boost delivery and improved performance for towing, daily driving, and high horsepower builds.

Frequently Asked Questions
What does the hot side intercooler pipe do?
The hot side pipe carries compressed air from the turbocharger to the intercooler. Upgrading to a larger diameter pipe improves airflow and reduces boost restriction.
Will this increase horsepower?
While the pipe itself does not add horsepower directly, it improves airflow efficiency which helps support higher boost levels and performance modifications.
Is this kit a direct bolt-on upgrade?
Yes. The Wehrli WCF100708 intercooler pipe kit is designed as a direct replacement for the factory driver side hot-side intercooler pipe on L5P Duramax trucks.
Will this work with stock turbochargers?
Yes. This intercooler pipe kit works with the factory turbocharger as well as upgraded turbo systems.
Do I need tuning for this upgrade?
No tuning is required. This kit improves airflow and reliability but does not require engine calibration changes.
