If you're looking to unlock the full potential under the hood of your 2011-2016 GM 6.6L Duramax LML, look no further than the premium Intercooler upgrades we offer here at Alligator Performance. Upgrading to a new intercooler is a great way to run a more aggressive tune without running into a ton of hassles. Each one of these aftermarket components is less susceptible to heat soaking, meaning you can stay out on the trail longer without losing any power. You'll even experience a slight boost in horsepower and torque over the factory intercooler, giving you plenty of confidence to tackle to more demanding jobs. Pair your new intercooler with some additional Engine Upgrades or Transmission Upgrades to get the absolute most out of your ride.
