Better than NGK?
On several boards it is written that AC Delco Iridiums are actually re-branded NGK Iridiums. Some of the posts are written by people in the parts business. They state AC Delco isn't making much these days and that almost everything from AC Delco is re-branded.
I was just waiting for him to say yes they are better than post this link.
