Well, I installed 2 ump intake systems in 2 of our rzrs today. It went fairly well, and the fitment is good. The modification to the airbox takes a little time if you want to get a good fit. And those 2 dam tiny bolts that go down by the shifter cable are a real bitch when you have monster hands lol I like the systems. They seem well built, and I hope they work as well as everyone claims they do. I have a few 4 day rentals scheduled for dumont, so I guess I will find out. Im just glad I can tell the renters to "leave the airbox alone" I will service it myself when it comes back. So is there anyone out there thats going to tell me they cant go 4 days in the sand without servicing? Speak up !! lol I need to know. All I know is those dam stock airboxes are incredible filthy even after a day!! So these have to be better.
