The Mishimoto Lancer Evolution 7, 8, 9 fan shroud kit will considerably improve engine cooling functions and the overall performance of your vehicle. All Mishimoto fan shrouds are significantly lighter than standard fan shrouds. In maintaining the lifetime of your engine, it is ideal to keep your engine running cool, especially during those unbearably hot days. A Mishimoto fan shroud will notably improve engine cooling performance by delivering more air to the Evo 7, 8, 9 radiator and driving out excess heat while at the same time serving another very important purpose; securing the fan blades. Which otherwise could potentially damage other essential components in your engine.
