I'm in the market for a radiator, summer is coming and temps are getting a little high when driving hard..

Basically I'm considering a Koyo (V or R) or Mishimoto, but I have a $40 greddy cap that I'd like to continue to use, because the koyo doesn't come with a cap and I'm not too sure about the quality of the mishimoto cap. Any idea if either of these radiators use the factory cap?

Another question, what do you usually see your intake temps get to under boost? at 80* ambient, 14 psi at 6-7K my iat was around 160. cruising usually hovers 10* above ambient.

my koyo uses the same cap; I would assume the mishimoto would as well

 

I can vouch that the cap will fit on the Koyo.
