Product Overview

This cold side intercooler pipe kit is designed to replace restrictive, failure prone factory plastic intercooler pipes on 6.6L Duramax LBZ and LMM trucks. The kit features a 3.5 inch mandrel bent polished aluminum pipe that eliminates sharp bends in the factory design, improving airflow to the engine for better power output and lower exhaust gas temperatures.

Common Faults & Replacement Symptoms

• Factory intercooler pipe cracks or split boots causing boost leaks leading to reduced engine power
• Increased exhaust gas temperatures (EGTs) and poor fuel economy due to unmeasured air loss
• Check engine light activation with boost pressure related diagnostic trouble codes
• Visible oil leaks around intercooler pipe connections indicating worn or damaged seals
• Audible whistling or hissing sounds from the engine bay under acceleration caused by boost leaks

Ideal For

• DIY diesel truck owners replacing faulty or cracked factory intercooler pipes
• Performance enthusiasts looking to upgrade their intercooler system for improved airflow and power
• Automotive repair shops seeking reliable, direct fit replacement parts for 6.6L Duramax truck repairs
• Truck owners towing heavy loads or using their vehicle for work applications requiring consistent engine performance
