DETAILS

Improve your cooling system while spicing up your engine bay with a Subaru Genuine  Red radiator cap. This cap is a higher pressure then the cap that came stock on your vehicle. By raising the pressure in the cooling system you raise the temperature at which it boils allowing it to hold in more heat. Some Subaru models have 2 caps, if you are trying to improve your cooling system you will need to replace both caps.

Notes:

  • This cap will not fit the BRZ/FR-S twins.
  • This is a 2 way valve, commonly found on the expansion tank.

JDM STI radiator cap

Wish Sti’s came with this piece stock. Way more aesthetically pleasing than the stock cap.

Totally agree! This should have been a factory piece. It is a small upgrade, but it really adds to the engine bay look. Thanks for your 5 Star Review, Basil!

Great OE replacement!

Replaced the crusty OE cap for this STI cap and it looks and performs great! If you have a STI, get two for both spots!

Perfect addition

I added this to a new radiator because the old one had a slight crack in it. The pressure relief appeared fine, with no cracks or leaks or issues. This is the perfect addition to my Upgrade.
