Spark plug question

[prplcar]

Just wondering if anyone has tried those e3 plugs yet? I am using Champion plugs now because they were listed in the install instructions (yes I read them, twice) that came with my Edelbrock heads. I had used both NGK and Champion in the past, but am interested to know if these e3's are worth the extra cash.

i dont imagine you would see any gains worth enough for the change

I'm running them but the jury is still out as I don't have enough time on the engine yet to say.

all those plugs do is make it so you dont need to index your plugs.they will make very little difference in a good running eng.if you are running a bit rich,they will burn a very small amount of the extra fuel.so some people will see a very slight improvement,most wont see any change.there is a reason these plugs come and go in the market,they dont really do what they say.

Mine does run a little rich. I am happy with the NGK's and don't plan to change.
