I've mostly used OEM, zuki's but picked up a few K&N's awhile back....may have even been before the issues arose. In any case, after everything I've heard + this, I'm not using them. IDK what exactly caused the guys issue...for all I know it could have been not safety wired and backed off because it was only finger tight or some other stupid human error, but it just isn't worth the risk if there is a miniscule chance it is a faulty oring design on the filter
Think if it was doubled up it wouldn't have made it 75% of the way through the twilight, can't say for sure because I didn't look at it after. There is this too:
if that's true, I'd guess there would be talk of it on their boards.
