I read the 50 plus responses to a recent post regarding K&N filters. There is one item that no one mentioned. If you remove the air box lid you do not have to risk water and mud entering the air box. I personally run a K&N with outerwear and also run an outerwear where the lid used to be and where the snorkel used to be. I ride in sand, mud, water, and dust and have no problems. I also change my filter after EVERY ride. Make sure you buy the outerwear that is water resistant.

you CHHHHHHHHHHAAAAAAAAANGE your filter after ever ride? dam that would be expensive or do you just clean it after ever ride?

 

I replace the filter with a clean K&N after every ride. I have a total of four filters to rotate so the oil is always dry. By the way, the reason I replaced the stock plastic snorkel tube is water would enter through it when going through deep creeks. Since having outerwears make a custom cover that is water repellant where the intake used to be and for the airbox lid I have solved my problem

 

got yea!
