Type-A cap style common applications:

2015-2021 Subaru STI

2015-2021 Subaru WRX

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.

Specs:

  • 1.5 BAR
  • 21.8 psi
  • Steel cap with electroplated black finish
  • Premium silicone sealing elements for long lasting durability
  • Designed for mini size (32mm ID) radiator necks only

This item is non application specific. Please verify compatibility for your application prior to purchasing.

Nice quality cap, and presentation!

Be careful on what PSI (Bar) you order! If you’re not tracking the car I advise you stick close to stock albeit being on the stock radiator! I went 1.5 Bar on the Radiator and 1.5 on the upper coolant tank! Constantly checking for leaks and such! I also am running the 4th cylinder cooling mod however that

Doesn’t make that much of a difference in this scenario! Caps are built tough and you visually can see the extra effort that went into the pressure rings/plungers on these.
