The GrimmSpeed Radiator Cap - Type A - 1.3Bar is a high-performance cooling component designed to enhance your Subaru's engine cooling system. Engineered to increase system pressure from the stock 1.1 Bar (16 PSI), this radiator cap improves heat dissipation and reduces the risk of overheating during aggressive driving or track use. Constructed with durable materials, it ensures reliable sealing and consistent pressure regulation, which contributes to optimal cooling efficiency. By raising the pressure capacity, this cap allows your cooling system to operate at higher temperatures safely, supporting increased engine performance and longevity.

Designed specifically for Subaru vehicles, this radiator cap fits models requiring a 1.3 Bar (19 PSI) pressure cap. It is suitable for use in street, track, or performance applications where enhanced cooling is desired. The installation is straightforward, replacing the factory cap with a direct bolt-on upgrade. The kit includes the cap itself, providing a simple yet effective upgrade to improve cooling system performance and reliability under demanding conditions. Compatibility is ideal for Subaru models that utilize a 1.1 Bar cap, making it a practical choice for enthusiasts seeking improved cooling efficiency.

Overview

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!
