Increased pressure raises the boiling point, which in turn reduces the cavitation at the water pump impeller. This allows the pump to run at it's intended efficiency range, which is critical for an engine utilizing a higher than stock rev limit.This High-Pressure Radiator Cap decreases the chance of hot spots or localized areas around the combustion chambers that could cause the engine to over-heat.This cap's control of engine temperature is a vital to an upgraded cooling system and is a must when seeking maximum engine performance.
