The Mishimoto Mazda Miata 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, and are a direct OEM fit.A Mishimoto fan shroud will effectively drive out heat from the engine bay and deliver a significant amount of cooler air directly to the Miata aluminium radiator.At the same time the fan shroud 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.
