I saw one of these K&N filters fail on a BMW S1000RR during a recent club race day. The unit was bleeding oil around the hex nut. Owner stated that the filter was applied by hand without putting a spanner anywhere near that hex nut. Luckily there were no issues for the rider other than to think about how much money he wasted buying the bulk pack that is now going in the trash can. I agree with LR and the others, OEM filters always ... even it means paying extra or having to drive around to pick one up.
