Intercoolers for 2004 - 2005 Chevy GMC 6.6L Duramax LLY. Heat is one of the biggest threats to overall powertrain longevity. As a gearhead, battling excessive temperatures is an ongoing trend. However, there are a multitude of various condensers designed to tackle high temperatures. One of the biggest changes to excessive Exhaust Gas Temperatures is to upgrade your factory intercooler. The factory unit is subpar at best, debilitating any efforts of overall heat reduction. To only enhance the shortcomings of the factory cooler, over time it becomes plugged with bugs, dirt, and other debris, severely hampering its overall cooling capability. Aftermarket intercoolers feature larger end tanks for greater air flow, thicker and denser cores, and just overall better construction. All of these same upgrades are also built into most of the upgraded radiators and transmission coolers as well. Also, we carry a wide selection of upgraded intercooler boots in silicone and Nomex and as well as clamps to insure you do not have a problem of a (blown boot) or the failure of the cheap rubber ones.
