E3 plugs in a 5.7 hemi
 

I have a 2010 ram. i have 125k miles on it. thinking of putting the e3 plugs in it to help with fuel mileage and power. should I do this or just get it tuned up. i just got it and don't know it's history.

Moved to 4th gen.

I had a 2010 Ram 1500 Hemi. My experience is as follows:

• Different plugs made no difference in fuel consumption
• With one type (can't remember which), I discovered a slight flutter on acceleration after eight or nine thousand miles
• The factory copper core plugs never gave me a problem and in fact will go a bit longer than the 36,000 mile recommended change
• The factory-style copper plugs were cheaper.

Best regards,
Dusty

Im running the E3 plugs in my 2013 Hemi, an my truck runs a million times better.

Just what is it that is better?

Fuel eco is better due to a better burn. engine performance is better as well.

If you google for results of these plugs, you'll find positive feedback from places like Horsepower TV etc. and primarily negative feedback from individual users. I tried them in an 01 cavalier 2.4 and in an 09 ram 1500 and found that they ran fine, but provided zero improvement in power or economy.

Some guys swear by them, some say they run worse. There's no reason for them to work any better as the voltage from the coil doesn't care that the ground electrode is a funny shape. It will spark from the center electrode to the single point on the ground electrode that has the least resistance. As long as the gap is correct for the application, they will run no better or worse than any decent quality plug. No hurt in trying them if you like, other than in the wallet.

What they are better at than NGK, Bosh etc. is marketing.
