Wanted to give an update on the velcro trick. I had to pull mine back off, it seems the velcro is "slippery" enough (even the hook) that I have the filter falling off every couple of hundred miles or so. I have removed it and just tightened the filter down on the housing. I will update as I have results, but it fell off 4-5 times in the last month or so with the velcro. Man does it run bad when that happens!
I wish K&N would just fix this with a new housing that has a lip to hold the filter in place, and one that doesn't break if you tighten it down a bit. Hopefully Troy is still following this. I have to say, this is the most trouble I have ever had with one of these, and it's making me consider just going back to stock.
