Why Get a Subaru STI Radiator Cap?

As you enjoy the full potential of the BOXER engine in your Subaru, you may find that the coolant boils out into the overflow tank, and possibly all over the ground which can be dangerous if you're still driving. By replacing your stock radiator cap with this 1.3 Bar STI radiator cap, the overall pressure of the coolant system is raised to just shy of 19 pounds per square inch. This also raises the boiling point which reduces the chances of the coolant escaping the system into the overflow tank or the ground. We recommend speaking with an expert to ensure that raising the coolant system pressure is right for your Subaru model.
