What do you mean by push the tubing into the airbox? The filter only mounts on that little plastic ring inside the airbox, so i'm not sure what i would be "pushing" into it. The filter only has that little lip inside the airbox to mount on.Actually, it is a pretty good piece. Getting it is the problem. I have been running one since it first came out as it was the first to come out and I like it. As far as getting the filter to stay put, I have had no problems. Push the intake tubing into the air box, hold it in place, slide on the filter and tighten it down making sure the clamp is behind the rolled end of the intake tube.
