so guys im not sure if this is the right spot for this post if not feel free to move it, but my question is: has anyone had first hand experience with these E3 Diamond fire spark plugs in a na build lsvtec to be exact with wild compression.

ive read mixed reviews on them, some say they helped tons in throttle response other say they made it worse, reviews were from all different types of vehicles

so has anyone tried these on the b series engines?

 

Lame plugs if u asked me, the extra grounds on these plugs takes up air n fuel mixtures in the cc

 

I use them in my F20c engine in my L7 replica. Seem to work fine. Talked to their tech guys at the PRI show in Indy a few weeks back. They have their plugs running very well in F20c powered race cars, albeit colder ranges than most run on the street. Will let you know how they do on the track.

 

have you tried taking an actual measurement of CC's to verify just how much the difference is? I wouldn't know either way as I have only used NGK IR an LIR plugs but am curious what the actual difference could be or if it's more car hype lol

 

Really? You think that a spark plug is going to make that much a difference in cc's? I would be more inclined to think it could bump up compression.

 

First of all, the hype that it makes more power would need to be tested.

I would be more concerned about those extra ground straps causing issues withbthe flame front. I have yet to see any real improvement on a dyno.

Testing ive seen has gone the opposite with these plugs.

 

It's getting ridiculous when spark plugs are the hype for power LOL. Copper NGKs for me all day long please. Cheap and there are literally no studies to prove platinum/iridium do anything more than last longer. Everyone knows copper is the best conductor of electric current, it just wears down faster. Anyone who is on top of their build keeps and eye on the plugs and every component for that matter respectively.

 

Do NOT run these spark plugs, the flame is not in a constant spot when firing, this will cause misfires, not to mention they are pure **** plugs.. period.

If its not a NGK or Denso, dont run it. I've yet to have any successful power gains by "cutting" the ground strap.. or angling it a certain way. The cheap plugs will perform as such..
