autolites are not the same but are considered to be the closest to motorcraft. I will always shoot for motorcraft 1st, autolite 2nd & never consider anything else in a ford. What ever you do, don't fall for those plugs with multiple tips or so called capacitors that store the spark. Why on earth would you multiple tips when the spark only jumps to one tip at a time anyways? They do not arch to all 4 at the same time!!!! They are gimmicks that people fall for!!! It's all marketing and that's it.
