So can anyone honestly say E3'2 live up to the fuel mileage claims? Taking a cross country trip in my Ram next week and need all the fuel miles I can get. I have read mixed reviews online from they work great to people who say they have engine misfires in a few thousand miles. I did a plug change 6 months ago but would be willing to buy a set of these to squeeze out another mile to the gallon. But the last thing I need is plug failure on a 4k mile round trip ride.

 

I doubt that changing out plugs that are still good to new ones would see little (if any) change in MPG. Now if changing worn out plugs, yes.

 

I only have about 6k on them. i have seen the claims by the manufacturer of something like up to 10-12% if I remember correctly. I know the one tv show tested and claimed they got 8%. If it would work it might be worth it but like I said reviews range from one end of the spectrum to the other. Not sure it would be worth the risk of a plug failure that some have reported.

 

Spark plugs that cost $64 for a set should last a lifetime. Not worth it IMHO.

 

exactly how do you know.. the spark takes the path or least rezistance/ weather 1 electrode or 4 it will only spark to one. and the spark will be the same. the only way to trully get a stronger spark is to go to better coils caps rotors and ignition box

 

Either that, or should include one free hooker. I swear, you guys need to quit believing this crap espoused on TV. Just because it is claimed that mileage will increase 12% doesn't make it true. Hell, if you want to believe myths, then dump some acetone in your tank.

 

The only thing that has ran better on E3s for me was a 6HP Briggs and Stratton lawn mower engine. ANd I could gap that plug.

 

Actually if you look at the e3 it really 1 electrode. It has three, but they are all connected at the top. I've actually bought an e3 spark plug a messed with it a bit to see what it does. It doesn't spark to just one electrode, instead it sparks to the whole electrode.

 

yeah....i have the e3's. im not impressed with them at all

 

In all honesty, I like my plugs. They work good in my truck and I FEEL the difference. If that's what you prefer, go for it. I don't see the need for people to knock 'em so much. Especially if they haven't used them. I bought them out of curiosity. NOT because the TV told me to.
