Understanding that increasing cooling system pressure directly impacts performance is crucial. While the factory 1.1 Bar (16 PSI) cap suffices for daily driving with a full antifreeze system, those pushing their Subaru harder or engaging in track use may opt for an anti-freeze/water blend for superior heat transfer and dissipation. However, the drawback of this blend is its lower boiling point, potentially leading to overflow in the expansion tank.

Upgrading to a radiator cap with a higher pressure rating is the most straightforward and cost-effective solution to this issue, ensuring your preferred cooling fluid stays where it shouldwithin your engine and radiator. Enter the GrimmSpeed High Pressure 1.3 Bar Radiator Cap, a quality and budget-friendly choice to unleash your cooling system's full potential and enhance the aesthetics under your hood.

FITMENTS:

• Compatible with all Subaru Radiators and/or Expansion Tanks
