Race Line, High-Flow Fan, 12"Provide your radiator with the maximum amount of airflow with our new 12in Race Line fan. Our Race Line fans were designed for heavy duty applications where a Slim Line fan just won't cut it. However, this robust fan is still thin enough to fit between your engine and radiator in most applications and provides 1850 CFM of airflow to cool the largest and most powerful of engines! For universal installation, use the Mishimoto Electric Fan Mounting Kit.
