With 23 years of documented research and development in the forced induction field, AMS Performance has proven itself as the powerhouse in the automotive aftermarket. Our award winning performance systems are what all others are measured by.

Royal Purple® Purple Ice® is a high performance radiator conditioner in a 12oz bottle. Its advanced 2-in-1 corrosion inhibitor and wetting agent provides year-round defense against corrosion and reduces the surface tension of the radiator coolant to help reduce engine temperatures.


Extensive testing confirms Purple Ice reduces coolant temperatures better than comparable products while providing extra corrosion protection.


  • Reduces coolant surface tension to allow greater heat transfer, resulting in lower coolant temperatures
  • Reduces hot spots in the engine and cylinder heads, reducing the possibility of engine failure
  • Helps prevent overheating, keeps the system clean and extends the life of the water pump
  • Purple Ice is safe to use with water-only or antifreeze / water blends
  • Purple Ice is compatible with OEM and stock replacement coolants, including extended-life antifreezes
  • Purple Ice does not contain glycol and is safe and legal for track use


  • For use with 50/50 antifreeze / coolant mixture: 1 oz. / quart of cooling system capacity
  • For use with straight water or higher water percentage antifreeze / coolant mixture: 2 oz. / quart of cooling system capacity
* Minimum of 20% antifreeze is recommended in street-driven vehicles. Purple Ice does not provide freeze protection. Use an appropriate amount of antifreeze for the cold temperatures in your area.
*Purple Ice should not be used in new radiators until anti-freeze has been cycled through the system.
