Mishimoto has released a performance intercooler for the 2001-2005 Chevrolet/GMC 6.6L Duramax. A high-performance diesel engine requires a cool, dense charge of air to reach its full power potential. Upgrade your factory intercooler to the Mishimoto all-aluminum intercooler engineered to maximize the efficiency of your Duramax. The Mishimoto Duramax intercooler is built to last, with heavy-duty cast aluminum end tanks and a bar-and-plate core, allowing for increased airflow and cooler intake temperatures. The Mishimoto Duramax intercooler features a significantly larger core than the factory unit and is designed to support substantial boost pressures and lower EGTs, both highly advantageous on your stock or modified 6.6L. Offered in black or silver, the Mishimoto 6.6L Duramax intercooler is protected by our signature lifetime warranty. TECH SPECS Mishimoto, the world leader in performance cooling products, is proud to introduce you to the Mishimoto Performance Intercooler & Piping Kit for the 2001-2005 Chevrolet Silverado.
