I was wondering if anyone knew much about these new E3 spark plugs...
I've heard a few good things about them such as giving you an extra 5 HP.
I've just never been a firm believer in throwing high dollar ignition parts on a stock or mostly stock 5.0.
But I just wanted to see what everyone's opinion was on these...
Also, does anyone know who makes these? Denso, NGK, Champion??

E3s suck. I think they made my car run worse when I tested them
no joke man, i put some in and about week after, I accidently flooded it (yes, i flooded a fuel injection lol, which ive found out isnt hard if you tps is messed up) Well that screwed them up, i let the car sit for about 30 mins and fired it about and it run like crap, it fouled out 3 of them and i didnt even wanna hassle with them so i threw in some $1.79 motorcrafts. whole lot better than that junky $6 plug
