I know that I had seen a post earlier where someone else was looking for this filter also R2C PF13000S . I had a lot of trouble with the Polaris air filter just like everyone else. I had switched to the R2C filter if I remember right I bought it from Desert Craft in 2015. It has been a great filter that is cleanable but I figured it was time for a new one last fall and I couldn't find it available any were anymore. I was servicing the rzr and thought I would do a search and see what came up and its available in several places again. I ordered it from Rocky Mountain ATV it looks a little different from my old one but the seal is thicker then a stock one and looks as good or better.
