2007.5-2010 GM Duramax 6.6L LMM Intercoolers

A brand new Intercooler might be just what you need to get an extra boost of power and performance for your more extreme applications. One of the benefits that comes with upgrading your factory intercooler is the increased levels of both horsepower and torque you'll experience each time you get behind the wheel. A new intercooler will also help accommodate for the increased boost pressures that comes with custom tuning or a complete turbo swap. Whether you're towing a heavy load or challenging new terrain, these intercoolers will help push your truck's performance to the limit while ensuring your engine remains under control. Pair your new intercooler with a new Cold Air Intake or some new Turbo Upgrades to completely set your truck apart from the rest of the pack. GM Duramax Fitments: 2007, 2009, 2010 GM 6.6L Duramax.
