During the last trip to Silver Lake July 7th Dunepilot and Pilotman decided to follow me up to the Manistee and check out the trail system, when we got there and unloaded it didn't take very long to figure out this ride was going to be dusty. As you can see I am still getting a little dirt leaking by around the edges and need to change my sealing design a little. The back side of the filter. I am glad I was using the pre filter this weekend or I would have went through 3 to 4 air filters :-) More on my pre filter.
