Replace the failed intercooler in your 1999-2003 Ford 7.3L Powerstroke and get your vehicle back up and running. 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. You can find factory-style replacement units as well as upgraded intercoolers that provide more durability for elevated boost pressures. Mishimoto, AFE, Banks Power, CSF, and XDP are just some of the top-quality brands that are offered for your vehicle.
