You guys that have the uni fall off or have trouble with the soft inlet flange that the uni is connected to,,, good grief !! What I did was simple to cure that issue and it cost me just over a dollar. Go down to your favorite hardware store and browse in the plumbing section. First measure the inside diameter of the inlet flange,,,, it just something over 3 inches ( forgot the exact size). With your ruler in hand dig around in the plastic drain line section where all the elbows and connectors are kept in bins. Since it is drain connectors they are white plastic.....ok.... You will find white plastic union connectors that are made to join two pieces of line together. One of the connectors is the right size that will fit snugly inside the soft rubber inlet flange. Give your dollar to the pretty young thing at the counter,,,dont forget to ask if she is married and if not offer to take her for a whrl wind ride in your UTV when the filter is on right and will not fall off and dust your precious motor. When you get home slicken up the connector and slide it inside the flange. Now slip on the uni and tighten the sh!t out of it but not too tight to cut in to the flange on the uni. Grab ur cell phone and call up the "pretty" you just met and give her hell (your talon not her).
PS: you may need to cut the length of the plastic for a good fit,,,, I'm a old dude and forget some things if I did that or not. I have since went to a r2c and installed a filter minder to keep a eye on restriction,,, so far the air box is squeaky clean. With that recipe I just keep a eye on the filter minder and take my air box off infrequently.
