Product Description

The Mishimoto MMICP-DMAX-02BK Black Intercooler Pipe & Boot Kit is a performance upgrade engineered for 2002-2004 Chevrolet & GMC Silverado 2500HD/3500HD trucks equipped with the 6.6L Duramax LB7 or LLY engine. Replacing the factory intercooler piping and boots with mandrel-bent aluminum tubes and DuraCore reinforced silicone boots reduces restrictive bends and enhances airflow through the charge-air system. This improved airflow helps support better charge pressure stability, improved throttle response, and lower exhaust gas temperatures during heavy use.

Each component is designed for direct fitment with the factory intercooler and mounting points, and the included constant-tension T-bolt clamps provide a secure, reliable seal. The durable polished aluminum pipes and resilient silicone boots stand up to the rigors of daily driving and diesel performance use. Backed by Mishimoto's Lifetime Warranty, this kit is ideal for Duramax owners seeking a robust upgrade to the stock intercooler plumbing for enhanced performance and durability.
