E3 Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new E3 spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines.

I am impressed with the plugs. I went from burning 3/4 of a tank of gas to only burning a half.

i run these in my daily driver c10 and it help the old dog 350. Run them in my pro street 81 c10 and they have a slight gain over other plugs as well as a longer life with the larger cams. And they work great in my old 64 gto with a stock 389 they just dont come with the little washers got to put them on yourself
