Does anyone know what cap would fit on a PWR radiator for a 92-00 Civic? I've seen posts on Fluidyne saying Prelude ones fit, but is this the same for PWR?

I bet the PWR one does .

Sorry couldn't resist... Oh and I don't know what stock one's will fit... (I'd imagine the stock one does though)... If not I hope they supply one.

Stock one won't fit, its too short, I had a Spoon one off my stock radiator, and it wasn't big enough. The PWR came with one, but its a 1 bar cap.
