Has anyone changed over to E-3 spark plugs?
If so, how do they work out and did the ECU adjust back to normal settings after any changes?

 

How would changing your spark plugs keep the car from still adjusting to only make stock power if it is still on the stock tune?

 

there made in China. do you really want that in your motor?

 

i have had them explode. i put them in my last car. it was a v6 and half of them where cracked or completely shattered

 

go with real brands like Denso's, NGK's, Autolite, or ACDelco.

 

Awesome.

 

ive heard only bad things about them in lsjs. hearsay though. x2 on ngks, densos and autolites. ive run densos myself. cheap and i had no problems

 

shitty shitty shitty spark plug. they fouled out in like 3 months in my car

 

Just think about the kids over at Southeast Asia before you buy them.

 

Just put the Bosch Platinum +2 in my car

 

No. Take them out and put Denso, NGK or Delco plugs in.

E3 spark plugs will eventually cause misfires just like Bosch plugs will. I've seen numerous cars come in with both and complaints of misfires. One truck even had 15k miles on it.

Look at the size of the center electrode material on a Bosch plug vs a Good plug. The Bosch plug is so cheaply made they barely use any platinum at all. There's no durability there.

 

Get them out of there... I dont know why autozone/Oreillys/advanced still sells those.

I used to be a manager for them and filed so many labor repair claims caused by Bosch plugs...

 

Regarding the e3's:
If you search there are several threads (horror stories?) on them-I was curious as well.

Here's something else I came across: E3 Spark Plugs TV : Featured E3 Spark Plugs TV // on the PowerTV Network
It's a clip on their website showing Stacy David from the show GEARZ at a Michigan Tech testing facility-if you look closely at the screenshots,etc. you can see that they're running a test on an LNF ! Looks to be making more power but how much and for how long?

 

i have these, no probs, but dont really see any improvements either.

 

Im running the 3787s now and dont like them. Going back to stock real soon

 

video is somewhat convincing, but doesn't say how long they last compare to a convinctional spark plug.

 

I`d seen the Stacy David video before, and that`s the kind of stuff I was looking for, real on the road reports.
I had no idea folks were so committed to making a better world for the people who probably could care less about spark plugs or our cars in general.

 

Whats wrong with them?

 

i run the new ngk iridiums 1 step colder. so far they are great.....stock turbo stock replacement copper plugs are fine.

 

So, there are more than one type of E-3, an Iridium, and 3787`s ?

 

No. theres only one E 3, its NGK iridium. asnd i have no idea what 3787 is.

 

i got them cause of stacey davids gears, saw them, they proved them. i needed plugs so why not try em out.

 

keep us posted about the E3's for next couple of days and report any notice with gains or problems.

 

ya for sure, they been in for bout a month so i'll check em sometime this week. let ya guys no how there working out. and ill post pics. if that helps.

 

my car had missfires like a motherf***** when i put em in!!
gapped em perfectly and everything...but my lnf hated een i pulled em back oum to be honest, wht after being in a week they were as black as the stock ones that have beem in there since 08 haha
