The 'Mishimotorsports' aluminum fan shroud kit, for the dual-pass race radiator, measures 22" x 18" x 3.5". Mishimoto aluminum fan shroud kits will improve engine cooling functions and the overall performance of your vehicle. They are significantly lighter than standard fan shrouds. In maintaining your engine, it is ideal to keep it running cool, especially during those unbearably hot days. A Mishimoto fan shroud will notably improve engine cooling performance by delivering more air to the dual-pass race radiator and driving out excess heat. The fan shroud will also secure the fan blades in place, which will prevent damage to 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.Fits Mishimoto's dual pass race radiatorHeight: 18" Length: 22" Width: 3.5" (including fan)Fan CFM: 1150Includes aluminum fan shroud and one 16" slim electric fanMishimoto Lifetime Warranty
