Provide your radiator with the maximum amount of airflow with our new 12" 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! Depending on your application, this fan can also be reversed and used in front of your radiator. For universal installation, use the Mishimoto Electric Fan Mounting Kit.
