Radium Engineering Radiator Cap Type B Black 1.3 Bar (18.9 PSI) arp These gears are to suit

These gears are to suit a 2JZ Oil Pump which is a common and recommended upgrade on 1JZ engines

So to seal the lower section to the upper we designed a dual stepped recess with the internal step protruding further down following the gas flow

- Generic use

- Bosch Motronic brought electronic fuel injection to Formula One in 1982 and the technology established itself quickly

Radium Engineering Radiator Cap Type B Black 1.3 Bar (18.9 PSI) arp These gears are to suitThe 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. NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks. Each OEM
