hey dukes dad,

Come on now....you seemed more intelligent then that. You mean to say you can't look at a product and tell how well it's made? How well do you think a spark plug will perform when it's side electrode was mounted crooked at the factory? That tells me that there was lack of quality inspections on the product. Wonder why there is already black soot buildup on the NGK's flat metal surface, could it be the plugs fire too weak? If so, won't need to worry about a hole in the piston with them then....lol.

I had 2,400 miles on my vehicle when I pulled the NKG plug and it looked like a plug that has been used for a year already....metal all tarnished....cheap cheap cheap. I have pulled Bosch plugs and they look like they were just installed still.
