Koyo Radiator

This is a necessity if you are running a Koyo radiator on your car. I was using a stock radiator cap on my Koyo radiator and it did not seal properly, so my overflow would overfill and my radiator would dump out all its fluid. This solved the issue.

It fits.

Don’t know why this wouldn’t be included with the actual radiator but imo is needed if your going with the radiator. Perfect fitment, no issues.

Good cap

Works as intended, good rad cap. Had issues with a previous cap not fitting properly on a Hyper-V Koyo Rad and this one fit well with no leaks. Also looks sick with the red/chrome
