The fins on your Mishimoto performance radiator, oil cooler, transmission cooler, or intercooler were meticulously engineered to provide the most efficient cooling possible. But, over time, bent fins can rob your cooler of airflow, efficiency, and good looks.
Restore your cooler's performance and aesthetics with this 6-in-1 fin straightener tool. This tool allows you to quickly and easily realign bent fins and return your cooler to its former glory. The Mishimoto 6-in-1 fin straightener tool features combs for most common fin spacings, including 8, 9, 10, 12, 14, and 15 fins-per-inch. Like all Mishimoto tools, this fin straightener tool is backed by our Mishimoto Lifetime Warranty for a lifetime of service.
