Overview

This intercooler pipe upgrade for the 2011-2016 LML Duramax improves airflow between the turbo and engine for improved efficiency, throttle response, and turbo spool-up. Intended for use with the OEM Y-bridge, this kit eliminates weak points in the factory design that can lead to boost leaks or complete failures. Includes a 3" High Flow Passenger (Cold) Side Upper Crossover Intercooler Pipe (20% increase over OEM), a 3" High Flow Driver (Hot) Side Intercooler Pipe (replaces factory two-piece 2.5” pipe), and a 3.5" High Flow Passenger (Cold) Side Intercooler Pipe (replaces factory plastic two-piece with 14 ga. aluminum one-piece). Features upgraded silicone boots to withstand higher boost pressures. Finished in custom powder colors. Pairs best with emissions-compliant tuning and drop-in turbochargers.

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.
