So what makes one plug idle better than the other???????

 

I bought E3s for my dodge truck, and I ended up getting worse MPG. It went from 11 to 9. Same driving. So... I dont think they are good for anything... Maybe less emissions.. MAYBE

 

I run E3's but haven't noticed any gain or loss.......'cept the cash I spent. I would just say go champion copper. I'll go back on my next change. Give the E3's a try if you want, it's all up to you. To each his own.

 

A good consistantly reproduceable spark.

Some plugs do that better than others.

 

You might consider changing to an injector that atomizes the fuel better than the single jet that comes stock. That might serve you better. The plug just fires whatever is in the cylinder. It only creates the one flame front. Now there is some debate as to the shape of the plug and how that effects the flames propogation thru the cylinder. This is the same idea along the lines of plug indexing.

 

I would recommend to anyone who loves there Dodge NOT TO USE E3 spark plugs!

I used these on mine and got three cylinder misfires, my truck ran like $#!T Switched back to the reliable Champion plugs and the problem magically went away. Not to mention the Champs are a 1/3 of the price of E3s. $60 versus $20...u make the call

 

they are $50 on summit, and yes id buy them again, unless i go to iridium

 

Spark plugs job is to ignite the charge in the cylinder. Multiple electrodes, exotic materials, grooved electrodes, etc, do nothing to enhance performance. You would get more out of an inexpensive plug, that you indexed, than you would out of the 10, 20, 30 dollar spark plugs the companies want to sell you.

What you want is a HOT, consistent, spark. Upgrading the coil, and ignition wires would be a better investment, than any of the 'gimmick' plugs. Sure, the exotic materials supposedly last longer..... and some actually do. That doesn't really offset the initial cost of the plugs though. Suppose that would depend on how long you left them in there..... after all, a fouled plug, is a fouled plug, no matter what it is made of.

Until someone can show me some hard facts, from a reliable source, that shows any of these plugs are worth the cost, I just stick with the regular old run of the mill spark plugs.

 

E3's are a hit or miss type of plug. I like mine. I felt a crisp response after I installed them. I've used Accel u groove's and champions so far and I still like my E3's.

 

i have MSD 8mm wires and an MSD coil also, but spark plugs are a touchy subject on this forum, everyone has their own opinions. he asked if anyone used them and if they liked them, i use them and like them, and i think im gonna drop out of this thread.
