Remove and replace the failed intercooler in your 2011-2016 Chevy/GMC 6.6L LML Duramax and get your vehicle back on the road. An intercooler is an important part of the turbocharger system on your turbo-diesel engine. The intercooler cools down the charge air before entering the intake manifold, after it is pressurized by the turbocharger. When replacing your intercooler, you can find factory-style units as well as upgraded versions that offer increased strength to handle more pressure. Mishimoto, AFE, Banks Power, CSF, and XDP are just some of the top-quality brands that are offered for your vehicle.
