Default e3 spark plugs

OK so a few weeks ago in one of the threads i mentioned that i was going to be trying the new e3 spark plugs. There have been a lot of mixed reviews concerning these and there performance. But despite the skepticism i decided to give em a whirl anyways. prior to install i was averaging 19.0-19.1 MPG after install Im now averaging 19.2-19.3 MPG. They aren't stellar numbers but hey every little bit helps. And the bonnie even seems run a little better. (im not sure how much of this is in my mind.lol) but bottom line i havent seen any negative effects from the plugs whatsoever. And as a plus you don't have to gap these plugs, their design makes it physically impossible. Just thought I'd share.

Pull them out and put in some Autolites and see if there'* a difference there.

The skepticism I have about new technology plugs is that you try them when you need to do a tune up anyway, and you do feel the difference because over time the old plugs have lost their performance and the new plugs give it back. That I believe is what many advertising claims hang their hat on and exploit.

I remember you saying something like that when I first mentioned I was going to try the new plugs out. And I think your theory makes perfect sense. In fact im almost positive theres some sales pitch file in one of these companies marketing offices that describes that very set up. But in my case when we pulled the old plugs out they looked almost brand new, I mean no wear or corrosion whatsoever, almost as if the previous owner had had the plugs changed before he sold it. So to my knowledge there was no peformance fall off from the old plugs.

No preformance boost from plugs, only loss from old plugs. Autolite coppers is all you need. I get mine for $2.59 a pair

I would just like to add that the ACDELCO Iridium plugs last forever. I love them, but they cost a little bit more.

I like to keep my arms free from the rear 3 plugs as much as possible.

Those one'* are a B****.

I'll stick to my NGK stamped acdelco plugs.
