I have a few of these available and more are always available, these are the 1.3 bar high pressure radiator caps for any subaru from 1990 to current,
The STi High Pressure Radiator Cap increases the pressure inside the radiator, thus raising the coolant boiling point and improving cooling efficiency. The open valve pressure is 1.3 kg/cm² compared to the standard 1.1 kg/cm². Easy Install. Made by STi Japan.
here is a pic of the cap

I see them on ebay from 40-50 plus 5-10 for shipping.
I am selling these for $39.95+tax picked up or shipped
