DerekClouser Posted September 14, 2017 Report Share Posted September 14, 2017 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.

Expand Yep. Was told even the HiFlo filters are no longer acceptable after tech-ing in on 9/11 at MidOh. Quote Link to comment Share on other sites More sharing options...
M_Quick Posted September 18, 2017 Report Share Posted September 18, 2017 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? Quote Link to comment Share on other sites More sharing options...

Even if you don't use the nut to put them on...which you are not supposed to. Quote Link to comment Share on other sites More sharing options...
