The Mishimoto Honda S2000 aluminum 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 stock fit. A Mishimoto fan shroud will effectively drive out heat from the engine bay while delivering a significant amount of cool air directly to your S2000 aluminum radiator. At the same time the fan shroud serves another very important purpose: securing the fan blades in place, which otherwise could potentially damage other essential components in your engine. All Mishimoto aluminum 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.
