I had a KN-138 that did the exact same thing this recall is for so be wary that it is a problem across the board with these filters.

 

Many tracks are banning K&N Filters because of this problem and MID-OHIO has actually banned all HEX Head Filters because of the failure rates.

Yep.  Was told even the HiFlo filters are no longer acceptable after tech-ing in on 9/11 at MidOh.

I'm glad my 700's use a internal filter. KN-112

 

So are these external filters just made poorly, or are people over tightening them when installing?

Made poorly. They blow out at the weld where the nut is welded on the front. Even if you don't use the nut to put them on...which you are not supposed to.

they're also known to blow through the middle of the hollow o-ring and have the bypass valve  break and block flow
