Overview

The Wehrli Custom Fabrication High Flow Intercooler Pipe Kit for 2011-2016 LML Duramax trucks upgrades airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool-up. It eliminates weak points in the factory design, such as boost leaks, and includes upgraded silicone boots for higher boost pressures. The kit features a 3" high-flow passenger (cold) side upper crossover pipe (20% increase over OEM), a 3" high-flow driver (hot) side intercooler pipe, and a 3.5" high-flow passenger (cold) side intercooler pipe, all constructed from 14-gauge aluminum and finished in custom powder coat colors. It is designed for use with the OEM Y-Bridge and connects to the factory throttle valve and grid heater, requiring no tuning and fitting stock trucks without other modifications. This product offers an 18% gain in air flow over stock for the upper crossover pipe and a 23% gain for the passenger (cold) side pipe. Proudly made in the USA.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
