When I installed my DNA air filter on my new XT I was surprised to find a K&N filter already installed! It was in there pretty tight and took some pulling to get it out, however when I installed the DNA filter the gap between the snorkel chamber and the filter was huge, a good few millimetres enough to see through to the holes I drilled in the snorkel chamber. It's nowhere near as snug as the K&N was and to be honest I'm a little concerned. Is this normal for the DNA filters? I plugged the gap with a healthy amount of grease but don't know if the air pressure might pull it loose. Does anyone else have this experience with these filters or any advice?
