im going to get some of these. i was told you drill a 1 inch hole in the side of your air box and just pop the suckers in.

Only problem with them is the foam gets clogged with dirt and then they do not really let that much air in. I had some like those on my 400EX and ended up removing the foam and just keeping the grills in so I could get the air into the box.
