I first came across this when I was browsing through youtube and came across a show called "GearzTV". I was immediately hooked on the show.. Basically the guy showed how to do custom work on cars...i.e putting a Ford V8 into a Mazda MX-5 (Miata) and new body work and stuff.
Anyways, the host endorsed these spark plugs called E3 Spark Plugs
Here's the youtube video....
GearzTV - E3 Spark Plugs
There are other videos out there where he visits a major research institute and discusses the plugs in detail... but from what I can gather, these plugs are pretty good.
There are mixed reviews online about and basically one or two bad experiences which makes me wonder if anyone over here has tried them...
So... has anyone tried them???
