E3 Spark Plugs
 

I was watching Horsepower TV this morning and they were compairing spark plugs on their dyno. E3 plugs improved HP and fuel comsumpion both. They addmitted that it was a more expensive plug but the pay back was there in fuel savings. Does anybody know anything about these plugs ? I need to change the plugs in my 500 EFI's this year and was going to use NGK's before I saw this.

I SAW THE SAME SHOW . I LOVE WHEN THEY DYNO THINGS I AM GOING TO GET THEM 5HP A LOT FOR JUST PLUGS:evilb: JEGS AND SUMMIT HAVE THEM

i saw the same show. the dyno test pretty much sold me. the extra hp has to be worth it. but, has anyone tried them?

And I've got a bridge in Texas for sale, too.

Sounds like the same hype that surrounded split fires a few yrs ago.

I watched it, they actually did a comparison of a few brands, and tested HP, and the amount of fuel burned during the dyno run. It was a good test, seemed thought out and even.

you mean someting on tv, is not true ? hard to believe.

i am going to try them in my rxt seadoo i will gps the install yhe plugs then gps i see if it make me faster???????????:Score-101010:

5 hp in a boat is like a 5 degree air temperature change. Not measurable and technically might be good for about .3 mph.

I will take the. 3 mph if i can get it.

one test doesnt sell me. and 5hp could mean a million other things. I will stick to the simple copper tops.
