Here are a few pics of the "install" (like it takes a rocket surgeon).
Stock filter compared to FRAM 8805
After the black ring stays in place all you have to do is slide it on the same way that the stock filter goes on. the black ring makes a stop for the filter other wise it can slide past the groove on the intake tube. here’s the end result.
hope this helps anyone looking for a good alternative to the factory filter. Not sure what other models this will work on, but mine is a 2010 RZR 50" for reference.
