That being said, it is well known that\u003cstrong\u003e raising the pressure in your cooling system has a direct correlation to cooling performance\u003c\/strong\u003e. The factory 1.1 Bar (16 PSI) cap performs fine for daily driving with a system full of anti-freeze, but for those who are looking to push their Subaru harder or run on the track may be running an anti-freeze\/water blend (or in many cases just straight distilled water) as it provides better heat transfer and dissipation than your standard coolant or antifreeze. The downside to running water or a blend of antifreeze\/water is a lower boiling point and thus you would easily fill up (and in some cases overflow) your expansion tank within a couple of hot laps.\u003c\/p\u003e\n\u003cp\u003eUpgrading the radiator cap to one with a higher pressure rating is the easiest (and by far the most economical) solution for solving this issue and keep your cooling fluid of choice where it belongs - in your engine and radiator.
