Mishimoto Mazda RX-8 aluminum fan shroud kits 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 OEM fit. A Mishimoto fan shroud will effectively drive heat out of the engine bay and deliver a significant amount of cool air to your RX-8 radiator. The fan shroud also serves 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.
