Well, its not my Prowler, but it does pertain to SXS's. I took the idea from my Prowler anyway. I mounted a 200 CFM 4000 rpm Mining ventilation fan (like a computer fan, only stouter) in my oil filter access panel and added a 2 prong plug in. Hard wired it to a fan switch in the dash. Took it out for a bout 5 minutes at 50 mph and shot the air coming out with my temp gun. 121 degree's. It puts it out at a lot of force too. The fan is noisy, but the motor drowns out most of it when its running. I also added a factory Polaris MTX front head unit and add on rear to it. It really cranks the tunes, now. Gonna mount the old sound bar (Swamp Monkeye) to the Prowler, gotta cut the x member out of the top of the roll bar and weld in new straight steel to make it work. I'll fire up the mig one of these days. But the RZR is almost set to go! All that's left is put my side mirrors on and add the turn signals sometime.
