E3 Spark Plugs- opinions? Hi, guys. I am wondering if the e3s are actually as good as advertised, or is it just bs like a lot of stuff out there. More particularly on LT1s. Anybody tried these? How were they with power, gas mileage, overall performance of the engine and durability? Or should I go with AC Delco platinum? 
P.S. the search can't do 'e3' because it's too short -.- . Well that surely sucks... Oh well.

A gimmick. AC Delco is just fine especially if your f-body is stock. All you need is the right spark plug gap and a healthy coil and you're good to go.
You can even go with NGK irridiums if you have stock cast iron manifolds since they are a bitch to change. They'll outlive your car. I still have them in mine.

they're f%&*ing junk in a performance application.....i tried them in my 355 when i had it and the motor ran like trash..........not to mention you cant change the gap on them.....save your money run a regular 3$ autolite, ac or ngk plug

I mean if you have a aggressive car that will get several sets of plugs a year and all that sure give it a shot. Really though IMO indexing made a bigger difference on OLD stuff with crappy chambers that had poor flame travel

I dont get the point of multiple electrodes on a spark plug. 2 or 3 weaker arcs instead of one strong arc. Maybe im wrong but it just seems like a hassle, plus how would you know if all the gaps are the same. Ive never had a problem with AC delcos in my GM vehicles.
There's only 1 arc.
