Keep your ride cool with a Zirgo fan and high performance UtlraCool cooling additive. Reduce your engine temperature by up to 30, reduce engine knock and predetonation and gain horsepower. UltraCool's scientifically-blended formula reduces the surface tension of your cooling fluid, enabling it to more fully penetrate the microscopic cavities in the surface of metal, absorbing heat more efficiently from the engine block.

UltraCool also lubricates water pump seals, preventing premature failure, and guards against electrolysis and the corrosion of copper, cast iron, aluminum, brass, steel and solder.
