I have serious space issues with my new PTE turbo installed and had to loose both stock fans. My Intercooler kit came with a FAL 12" slim fan rated at 1000cfm but my coolant temps got to high under normal driving conditions. (216+) I ordered an 8" Zirgo fan and wired it to my AC fan plug and when it's running, it moves more air then the 12" FAL.

So I just ordered one 12" and one 10" Zirgo fan to replace my other slim fans. I'll use the small 8" fan as a pusher in front of my AC condensor.
