That's like the oil companies who pay to get their names on the side of the car, while everybody in the pits is using something else in their engines. I'd be VERY surprised to find those plugs actually used by professional engine builders, regardless of how much the company paid for the name on the car! How much STP do you really think Andy Granatelli put in his Indy car engines?
