Need help to ID a Champion spark plug N-14LY
Hello everyone. I worked for AMC/ Jeep (before Chrysler bought them) for over 9 years. While cleaning my garage, I found 34 brand new Champion N-14LY spark plugs.
I can't remember what AMC or Jeep engine these plugs were for. Anyone remember?
I have done an exhaustive search on the Internet for this Champion part number but have found nothing.
Any help wouild be greatly appreciated.
Kind regards, Al Gainey
