Royal Purple Purple Ice – 355ml

This Royal Purple Purple Ice cooling system treatment improves heat transfer, lowers engine temperatures and shields the system against corrosion. It works with both modern and high-performance engines, so it suits fast-road, track and motorsport use across the UK. As a result, your cooling system can run cooler and more efficiently under demanding conditions.

Because it reduces coolant and engine temps, Purple Ice helps prevent overheating and detonation. In addition, the advanced formula protects aluminium and other metals from rust, scale, electrolysis and corrosion, which supports the long-term health of radiators, water pumps, heater cores and coolant passages.

Compatibility: OAT, HOAT, ethylene glycol and propylene glycol blends. It also works with straight water for track use where permitted.
