Input on E3 Diamond Spark Plugs

**SajoR** · 07-06-2010, 12:30 PM

Just wondering if anybody has ever messed with the E3 DiamondFire spark plugs or heard of anything.....

Only reason I'm asking is cause I overheard I guy preaching about them in his TransAm here at a local car meet/get-together. Didn't bother to ask other people about it cause I was already leaving when I overheard the guy.

I know that the NGK TR55 are overall the plugs to go with, so I'm just looking for some input on these. Curiosity got the best of me, figured I'd ask here.

Well, I don't know of anybody else that has them, so I purchased a set for the hell of it, going to put them in and compare them to the NGK TR55s I have, if any difference at all. I'll let you guys know what I find. I don't have any actual equipment to give any numbers, so I'll just have to do it from feel and take notice. I'll have a friend with me so I can have a second opinion as well. Let you guys know on my findings.

Advertising hype. A couple of members have tried them and ended up with issues. NGKs or Iridiums imo.

I had iridiums on my z28
I felt no difference
Wit the rapid-fire car felt alot better
And I was told that iridiums delco are the right plugs for ls1

Let us knw how it goes

You won't feel a difference from one plug to the next unless there is something wrong.

Stick with the NGK's or the Delcos.

Agreed.

E3 is nothing but a gimmick.
NGK TR55's, ACDelco's, or AutoLite AR103's.

Personally running AR103's.

Any plug with more than one electrode is pointless and a waste. Distorts spark.

you sure get from CO to TX really fast.....

**SajoR** · 07-07-2010, 10:41 PM

Lol you guys are funny....but anyways so I haven't done the test yet seeing as how my damn fuel pump crapped out. But maybe, it's for the better seeing as how I've been reading what you guys have been saying about these spark plugs lol. Either way, it's a good thing I had changed the plugs cause apparently my car is running very rich....NGK's were fouled pretty badly =(.....so now I have two problems I have to take care of.

Time to return the E3's and get new NGKs I guess, a new fuel pump and figure out why she's running so damn rich.
