The CSF radiator is amazing but pairing it with the OEM cooling fans leaves little room to work on your Nissan or Infiniti. Lucky, Mishimoto makes a cooling fan (shows that it only fits a Nissan 350Z) that fits very well and the only reason why I know this is because I just installed on my Infiniti G35 Coupe and I still have room to snake a tool or two. I would 100% recommend pairing those two together.
