I am looking to possibly upgrade my radiator. ZZP sells a 1 5\8" for $234 shipped. I can get a 1" stock GTP radiator from advanced auto or Autozone for about $190 or a wbodystore 1" for 197 shipped. Chime in on your experiences with a ZZP or wbody radiator please. Remember my GT is lightly modded but not in a way that will create extra heat except the PCM.
