"In laymans terms it simply extends the spark duration so that the combustion burns more of the fuel." So if I hold the match in the gas puddle longer, it will burn more complete(not to mention my hand). These gimmicks have been around for years. back in the '80s, there was a similar product(cant even think of the name)...sold a million of them...didnt do squat. ex. if your ugly and I tell you that your good looking, if you believe me...get the picture?
