Quickford1, was using AR473s ohm tested each one before installing, after putting 2 sets in and engine still would not run correctly I punted and changed the brand. Bottom line was new plugs fixed the problem the brand was most likely irrelevent. I've ran auto lites for many years and have good results, however after that episode it will be a while before I try them again. Not an NGK fan but that was the easiest plug to get as my application uses an odd plug configuration.
