Ok. I did the air box mod. But I am not all together happy about the amount of junk that can get in through the side holes. My DRZ had the snorkel removed but it never had any issues with water getting into the air box. It seems every time I go out I have collected lots of water in the air box along with a film of mud... I drain the air box and put the little cup back on and then repeat next time out. Has anyone else tackled the side holes or maybe some air filter foam artfully placed over the big hole to keep some of the crap out???
