Yeah me too. I have installed many different brand plugs in 30 cars, 5 motorcycles, snow blowers, lawn mowers and never noticed any difference. Could not understand when ppl would claim "my car ran like crap with X brand plugs but great with Y brand". Perhaps internal electrical resistance variation between brands is responsible? Heat range?
