I have seen many people posting on iATN having spark plug problems on Ford modular engines. I have experienced many of these problems myself. I made a presentation for my students about the different problems with the engines, and wanted to make it available for everyone else. I would be more than happy to hear if anyone else has more tips, or finds any errors. I am trying to make this the most complete and correct Ford spark plug guide, and this is my first draft.

Thanks, and everyone have a great weekend! [Ford Spark Plugs]
