Hey guys, my 16 z500 air intake really sucks in a lot of dust by the evidence inside the air filter housing and on my recently installed uni filter, so glad I replaced the stock. So I purchased a 30 PPI uni filter sheet and fabricated a pre filter that slips over the intake neck between the seats. I replaced the stock push pins on the cover panel with push rivets that are user friendly to remove. I hot melt glued the filter ends together and oiled in the same manner as my primary intake filter. I haven’t taken it for a ride yet, but I’ll update on the results. Any feedback on what I did is appreciated.
