HKS 1.1 Bar Limited Edition Radiator Cap

Looks great

Installed on a first generation cross truck with OEM radiator. Running the vehicle, hard or towing and full cargo. The STI cap seemed like too high of a spec no problems thus far after 1000 miles, no leaks, no overheating.

I went ahead and upgraded my cap because I heard the oems were not the best especially after a couple thousand miles. I put mine on the coolant tank expansion. The highest point where it counts

Super solid choice for dressing up the engine bay a bit, screws on super snug, and looks great, seems to change color based on viewing angle pretty dramatically as well. Kind of a cool little bonus feature.

Installed on the expansion tank on my 21 STI. Great part from a great brand. I do not recommend putting this on your radiator as it’s a lower pressure rating.
