STI Performance Radiator Cap Information from Subaru Superstore of Surprise, AZ

Help keep high engine temperatures under control with a Subaru STI Radiator Cap from Subaru Superstore of Surprise

The cooling system for your turbocharged Subaru BOXER® engine has a big job. When it comes to normal daily driving, the stock radiator cap is up to the task. However, when you're looking to get the most from your turbocharged Subaru WRX or Forester, it's worth upgrading to a high-pressure STI performance radiator cap. This way, your radiator is less likely to puke coolant all over the place during a track day or weekend drive through empty and winding roads.

What's the Benefit of a High-Pressure STI Radiator Cap for Your Subaru?

This STI performance radiator cap is engineered with a stiffer spring that increases the maximum cooling system pressure by nearly 6 PSI. This effectively raises the boiling point of the coolant so it will continue doing its job during the most demanding driving. When it comes to shaving time off your laps, there's no place for radiators that can't hold their coolant. That's why we recommend this Subaru cooling system upgrade.
