The Mishimoto fan shroud kit for the 1979-1993 Ford Mustang will considerably improve engine cooling functions and the overall performance of your vehicle. All Mishimoto fan shrouds are significantly lighter than standard fan shrouds, and are a direct stock fit. A Mishimoto fan shroud will effectively drive out heat from the engine bay and deliver more air to the radiator, while at the same time serving another very important purpose: securing the fan blades. The fan shroud will keep the fan blades in place, which otherwise could potentially damage other essential components in your engine.
