E3

I've seen results of these E3 spark plugs showing increase in MPG & a bit of power.

Has anyone use them in their jeep? I have a 2011 wrangler unlimited. Was thinking of switching the stock plugs for the E3.

What I would like to know is the long term effect of these plugs on the jeep. Please share your experience with these plugs if you have used them.

Thanks!

If you've "seen" the results why would it be different in a Jeep? Personally I don't see how they would make a difference from the stock plugs. Again, if the difference in MPG and power was so spectacular, why wouldn't the manufacturer use them to begin with?

I've read about misfires using those plugs.
I really do think the gains people see are from just replacing the older plugs.
Switch over to any new plug and you might see a difference.

I have read bad review about them but there is one regular member on the forum that swears by them and said he got increased mileage after changing them.

Stay true to the Toledo roots and use stock Champions. The Jeep and Champion plants are neighbors.

I'm more of a fan of NGK. Probably cause I've drove a japanese car for to long. The results I've seen were from a new built engine dyno tested using new plugs. Then dyno tested using the E3. E3 came out a lot better.

And I've also read about people having misfire problems.

And there are a lot of parts that are better than stock. Why doesn't factory just use that instead of their crappy parts? Exactly!
