Mine has never popped off. I have about 2500 miles on it.
I have not heard anything from Troy since 6/22/12. Correspondence with Steeda began on 6/7/12. My advice at this point is to buy Steeda. K&N has issues with their product, and I'm not sure they're willing to do anything about it at this point.
