K&N Air Filter Hack C109 Boulevard

Cut a square hole in the used airfilter and glue in a K&N high flow panel.
I did this with a C109 because K&N no longer make one for this bike.
I used K&N part # BM-8006 (for a BMW). I found a better fit with a dimension search on K&N but they were $30 each more expensive so I used this one.
Shout out to Darryl Boos video for giving me the idea.
