E3 DiamondFIRE Spark Plugs
I read a thread over in the General side a bit ago that reminded of E3 plugs. Has anyone used or heard of results from these things?

Save your money. A Standard replacement plugs is all you need unless you have done a LOT of high HP mods. There have been a number of dyno test of various wires and plugs and none of them have amounted to anything worth the extra cash!
Remember the old SPLIT FIRE Spark plugs. That was 100 % hype!
I imagine if you were running a standard 99 cent Walmart plug and then switched to a new rare metal plug, their may be a slight difference in HP but I doubt it. The rare metal fancy plugs were made to satisfy longevity of emissions standards more than provide a basis for more power.

I had a friend who genuinely believed the SplitFire plugs he put in his car increased the performance, but it had a lot more to do with fouled plugs that he replaced. This is just another variation on the SplitFire scheme.
