Mishimoto Mazda RX-8 aluminium 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. All Mishimoto aluminium fan shrouds include an adhesive protective strip. This adhesive-backed foam strip seals any remaining gap between the fan shroud and radiator so that the fans are only moving air that has passed through the radiator core as opposed to pulling in air from the engine bay, resulting in improved cooling efficiency.
