Spark plugs: Some expensive plugs claim to give you 10% better economy and more power. BULL!! Some will last longer in an old s**t box but in 40 years I've seen no difference in performance. Think..... the car maker would have done that if that easy.!!
I'm not into performance but can say you can mess with exhaust, intake and camshafts and get tons more power. MPGs NO! The newer your car the better off you are to stay with OEM stuff. T

Good point Tom. It's hard to look past all the "Poster Facts" you may get a brighter spark, but when driving, there are sooo many other factors that you can do to get you more mpg.... tire pressure, oils, exhaust to name a few...
smart driving is the biggest,

The old drag racers trick of "Indexing" the plugs was good for around 1/10 of a sec. Dont believe it did squat for MPG though.
I tell folks the most important things they can do for fuel economy is tire pressure, air filter and drive easy on the gas pedal.

Yeh, I know the drag racers do this but for the average grocery getter car I don't think it helps. T

If you think a little, you will see the "gimmick" plugs are just that. How many paths can one spark take to ground? 1,2 4, or a complete circle of constant spark. One spark can only travel to one ground, so the 4 prong theory is bogus from the start. It might make it so the ground electrodes do not wear out as fast, but all I have seen installed were removed before there was any chance of wear.
Being way2old is why I need help from younger minds

I always thought that too W2O, its a money gimmick, 2,3,4 prongs theres the same amount of spark in one prong the only difference is heat tolerance, I never seen any real evidence far as better gas milage.
