Many people here have used Bosch, actually a large percentage has, IIRC. But, a large percentage of those who have used them once have not used them again. I have had great success with Bosch plugs in others apps, but I wouldn't use them in a duratec again, there are simply better plugs for this application. Do I think you should remove your new plugs? hell no, but next time you go to make a purchase, at least consider what has proven to be a better product.
