Lonesome7.3

I just watched a thing on Speed about E3 spark plugs. I do not trust gimmicks and that is what the E3’s look like to me. I have heard that they do very well in small engine applications and even some imports. But I have also heard that they do nothing in V8’s. I am considering them for our old F250 with a 5.8 and I would appreciate any feedback from my fellow real truck owners.
