2011-2016 GM Duramax 6.6L LML Air Intakes, Intercoolers & Pipes

An aftermarket intercooler & piping upgrade is the key to maximizing the power output of any turbocharged engine, giving you an extra boost of confidence each time you get behind the wheel. Any one of these performance intercoolers and tubes will help improve the overall airflow efficiency of your engine, allowing for consistent and reliable operation of your engine in every situation. Many of these aftermarket components will even handle increased boost pressures brought on by aggressive custom tuning or turbo swap applications, keeping your engine under control during even the most extreme applications. Pair any of these intercooler and piping upgrades with new Cold Air Intake or some additional Cooling Upgrades to unlock even more potential out of your custom Sierra/Silverado.
