Here is a pic of my old Fram CA332 with the box. I "think" I purchased a new one around 2007 or so while my car was being built. I shoved the old filter in the box and still have it doh', so I'm not sure if Fram made the filters with round holes (original) & then the diamond shaped openings :dontknow:
Thanks for this post 73Scamp.......When the time comes to replace mine, I sure as hell won't be paying $300 for an air filter :disgust: I'll paint the K&N orange LOL
