Radiator Cap Type-B 1.1 Bar Black Radium Engineering

The radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature. A higher radiator pressure effectively raises the coolant boiling point, providing an extra safety margin and preventing air pocket cavitation at the water pump.

Available with 3 different pressure relief springs:

1. 1.1Bar (16.0psi)
