I've been wondering,If you have drilled holes in your air box does it get a lot of water in it in moderate water crossings.Ive done this and was wondering if water gets sucked in if it will ruin the engine.Im thinking about getting a K@N air filter and want to know if I should seal the air box and if K@N's suck in sand???Thyanks..

P.S.Buyou220atv rocks!!!

 

why thank you for the compliment...are you really sure that you want to drill holes in your air box though? I tried it but it made my machine run too lean.(actually I made a new lid) and also try this run your machine and ride it with the cover completely off ...notice how loud it is.. now imagine putting holes in the lid. it'll be almost that loud but not quite. just food for thought. That's the reason that I didn't put holes in my box because I have neighbors that don't like atv's in the first place and I don't want to make them madder with having a loud quad . I have heard that the K&N filters may suck in some small grains of sand, however, I have no experience with the K&N filter, I'm trying to keep my machine pretty much stock for reliability reasons. if other people have experience with the K&N filter then please let me and Peltrax know.

 

I currently run a K&N in my Xplorer. Didn't seem to effect the way it ran much. I think it may breathe a little better due to higher airflow. About the only real benefit I can see on a stock engine would be that it is washable if your stock filter isn't. They make an outer 'sock' for the K&N that will keep the water out of your engine, but I don't see why you couln't fit it over the stock filter. I have been told by more than one knowledgable person that the K&N will let more fine grit through than the stock filter. It was suggested to go to a hi-flow oilded foam filter if I wanted maximum dirt protection at a slight loss of airflow (but still better than stock). I have never noticed dirt in the intake of my machine, but I am very picky about how often I clean/oil the K&N, but after seeing dirty intakes on a few other machines that go through more dirt than mine, plus talking to a few people, I decided to go with the oiled foam.

 

the k&n is a very fine guaze material and oiled. i have one on my harley, dodge truck, and lakota i dont think its any louder either i dont go thourgh a lot of water but if i was i would just duct tape the houes dont worry about the sand either
