the tought has been crossing my mind about using the e3 plugs.
i have a few questions though.
1. how hard are the plugs to change on our cars?
2. they are only about $6 to $7 a plug, do you think they are worth it?
3. has anyone here used them?
4. if so, have you noticed a difference, good or bad?

thanks for any answers you give. will be starting on some simple mods for the car this summer after i get a new job and back on my feet.
 
I have used them on customers cars amd they seem to work fine, I didnt see any improvment performance wise but I would assume MPG and spark quality would be better, but thats just what the plug box says.
 
I tested them in my 3.8 buick and have noticed a 2+ mpg increase on the highway and about the same in town. I've logged over 10k miles since getting them (I take regular trips from Lincoln, NE to Houston, TX right now). I can't say for sure if there's actually been a power increase (as the buick is not worth the dyno testing). I'm considering using them in my SC when I get my new engine put together.

only thing ive been told is they work fine but burn out faster in our cars.
