I used to use K&N until I saw a You Tube video where someone cut in half a K&N and a Mopar/SRT Filter. I switched to the SRT filter after watching that video.
Switched to the SRT filter for my 6.4L at the last oil change. Did so before reading your article. Glad I did.
SRT oil filters are getting hard to find and are becoming expensive. Wix makes these filters for Mopar and it has an identical filter for much less. It is Wix #57063.
