I dunno, it looks awful small at the intake part, try running one of these bugpack air cleaners like Phil's got on his buggy, it looks and runs very well with it and there are several buggies out there with the same engine, but you are going to run a supercharger, so I would look at the air delivery to be a little larger than what they run so you don't have to worry about the filter collapsing on you, but you will never know, trial and error I guess. I am running thses baja style filter that has a 4" intake and 3" outlet.

You may have seen it before on the rail and the picture on here is a little hard to see it, but I also put a website link on here to show a picture of it a little better, you can get them at Shadetree Performance.
