Looks great
Hello,
Glad you snagged one! Looks great and does the job.

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.
Hello,
Thanks for the feedback! Great to hear it’s performing well with your Crosstrek, even under demanding use.
Regards,
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
Hello,
Thank you for your review! We’re glad the HKS radiator cap upgrade gave you added confidence!
Regards,
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.
Hello Alex!
Thank you for your 5 star review. We agree it looks great and is a nice addition to your engine bay. Thanks for sharing your feedback!

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.
Ralph,
Thank you for your 5 Star Review. The HKS Radiator Cap is a great choice for performance with a nice touch of JDM style.
