Can someone tell me what kind of Rad Cap fits the Koyo Racing Rad. I need one soon. Is there a Part number or Type that I can just go to any performance shop and ask for one. Instead of me ordering one and waiting for shipping.
Thanks

 

I'm waiting on a Koyo radiator myself. I've been told that a Nissan radiator cap will work. You should be able to pick one up at most any auto parts store.

 

Update: If you don't need or want one of the aftermarket radiator caps with a fancy label and premium price, go to your local autoparts chain and pick up a Stant radiator cap - Stant part number 11233. It is a 16 lb. = 1.1 Bar like the stock cap and it's a perfect fit. I paid less than eight dollars for it. The Stant caps for Nissan radiators that I looked at were the same overall size, but they were 13 lb. = 0.9 Bar.
