VP Racing Stay Frosty Race-Ready coolant is formulated for high-compression, high-heat racing engines. It contains a specialized blend of wetting agents that drastically improve the coolant's ability to transfer heat away from high-temperature cylinder heads. Temperatures of engines are reduced by up to 100 degrees F, compared to conventional glycol-based coolant. This increases the density of the air/fuel mix, and allows ignition timing to be safely advanced without the threat of detonationresulting in more power and torque. Ready-to-usejust pour it in Contains no slippery/hazardous glycol Reduces engine temperatures by up to 100 degrees F 100 percent water-based formula Maximizes horsepower and torque No-freeze protection for maximum cooling Non-toxic and biodegradable Blended with chemically stable reverse osmosis water
