I've got them. I found them easier to handle than the K&N- also a great filter. You do not want to remove the air box completly. As Reido113 says, some of your electrical mounts to it, but just as important, it block all the road crud from the rear tire. If you go to the FREAK- a great product, too- you will lose the chrome faux breather covers. I thought they were one of the cool parts of the bike, so I took a dremmel to my air box. It is wide open and I left the mounting points for the chrome covers. The bike rips with the mod. You will want to think about a rejet after the mod. One more thing- there is a sweet spot on the carbs where the filters sit- just play with it. It is pretty obivous where it is. If you miss it and overtighten the Uni's they will pop off. bennybmn is also correct about supporting the carbs. I'm cheap- I used a zip tie to the frame mount. I'll buy the rod end support this winter when I get the smooth bore 35's.
