The Mishimoto fan shroud for the Civic Si is a significant upgrade over the stock unit. The aluminum fan shroud is significantly lighter than standard OEM shrouds. A Mishimoto fan shroud will effectively drive out heat from the engine bay and deliver more air to the Mishimoto performance radiator. This fan shroud from Mishimoto will secure the fan blades, which otherwise could potentially damage other essential components in your engine. The Mishimoto fan shroud includes the aluminum shroud with two 10" electric fans pre-assembled and all necessary mounting hardware.
