Are the E3 spark plugs worth the money? Have heard both ways, but from nobody that has accually used them.

They ran a test on horsepower TV a few weeks ago and they made 5 hp more on an engine dyno while getting better fuel economy. They seem pretty high on them but again I've never used them and I don't know anyone who's used them but they're supposed to be real good.

If goofy electroded were worth anything like mileage and emissions gains that all the plug manufacturers claim then the OEMs would be all over it because to them a .1mpg gain is BIG money.

Also take into consideration how much they got paid to make those plugs look good.

Oh yeah I completely agree with that. I like the show but half the time I don't understand why they do what they do. Some of the decisions are rediculous. Still enjoy the show though.
