Yeah, those gargles are pretty cool. One questions though. I also did the KN filter and it really makes a noticeable difference. I haven't figured out how to keep it air tight. With the drop in square filter do I have to be concerned about air particles getting sucked in?
I noticed mine didnt sit perfectly in the space. I built some places up inside the airbox to make it seal off, but dang if I can remember exactly what all I had to do,.Been too many years.
Save a paper filter, too,, you can ride when the K&N is drying.
