Yipipidyyip.... The seal isn't great. I used some White PTFE grease that I had left over form my MTB days, it just needs to be sticky and fill the crack.

I also smeared some inside the airbox (the clean air side) - just in case!

I have a DNA filter, but it took three cleans to get all the dust/sand out of it. I'm not sure how the guys with paper filters faired (Nick ???). Never needed to clean it during the trip though.
