113061.A
Optimize Your Subaru's Cooling System Without Breaking the Bank! Let's face it engine cooling technology can sometimes seem like a dark magic that is impossible for us mortals to understand. That being said, it is well known that raising the pressure in your cooling system has a direct correlation to cooling performance.
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. Upgrading 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.
The GrimmSpeed High Pressure 1. 3 Bar Radiator Cap is a high quality and way to maximize your cooling systems potential and upgrade the looks under your hood without breaking the bank!
