I bought some NGK TR6 plugs off of Amazon because of their price. I seen some videos and forums about fake NGK plugs, which made me think twice about using them. I ended up purchasing another set of TR6 plugs from Speedway for a little bit more than Amazon. I'm glad I did. The print on the Amazon plugs have a darker print, which is a sign of a knock off and the boxes are different. No more Amazon parts especially since Speedway is pretty much in the same price range.
