THIS IS WRONG INFORMATION.....
geo-y-rock did the measurements and found the taper to be the same......i have used os plugs since day one with these motors....they work great....the only plg i had problems with was the od plug....they would leak...thr the plug, you had to kung fu grip em to seal them...
i will find the post by geo...
