Engine Ice Concentrated Ice Water CoolantConcentrated "Ice Water" high performance coolant improves the ability of water to wet transfer surfaces by 50% - providing a significant reduction in surface tension. With lower surface tension, heat moves away from the engine faster. Add one 12 ounce pouch to 5 gallons of water for race-level cooling performance. Lab-tested to lower engine temperatures and improves horsepower versus traditional antifreeze. Provides cooling protection only; contains no anti-freeze properties.Features: Concentrated just-add-water coolant mix Creates 3-5 gallons of high performance coolant when mixed with water Distilled water is prefered but works with tap or deionized water, as well For extreme racing conditions, use stronger 1pouch:3 gallon water ratio Superiorheat transfer over traditionalantifreeze For aluminum surfaces, up to 10x bettercorrosion and oxidation protection compared to antifreeze Protection for all engine internals, including aluminum, cast iron, brass, steeland rubber Superior protection of silicone seals and hoses Convenient for race travel / trailering / space savings Glycol free for most racing applications Biodegradable and less toxic than antifreeze alternatives Coolant only Note: Contains no freeze protection.
