i have e3 plugs in mine and there is a nice difference in power and gas milage. if you are going the e3 route (!!!DO NOT GAP!!!) THEY ARE PRE SET FROM THE FACTORY ANY TAMPERING WITH IT WLL MESS THE PLUG UP AND IT WILL BE sH@% AND NOT WORTH THE EXTRA MONEY you spent but go on the website and read all the info for your self. they also come with a 5yr 100,000 mile warranty i think. so good luck

I would agree with reading info, but not off their website. Do a google search and look at all the forum discussions, or just search in the LT1/LT4 section of this site.

No such thing as magic spark plugs, just magic marketing. I can't believe some of the TV shows that are endorsing the E3's.

E3's are worth about as much as the box they come in.....
