Re: Spark Plug Upgrade
Please read what I wrote, I wrote it that way because that is the way it works, no need to re-confirm what I already wrote, I don't think.
I do not use Iridium type spark plugs in anything but what they are designed to work in, the hotter sides of multiple spark plug emissions cylinder heads. That means, NOT in American engines.
There was just a discussion about a certain type of spark plug for American engines, totally not workable for what they are being pushed on today. Anyone ever have a two stroke outboard engine that used a very strange spark plug, a "surface gap" type? The firing end of the plug is flat, looks a pancake, with a center electrode and a full round band of porcelain around it, in a large hole in the end of the body, NO side ground electrode.
We spoke of these plugs and what they were, what they were used in, their history, function, and other things, in the topic, which was about heat ranges, plug gaps, and these spark plugs are extremely cold, and only designed for serious electronic CDI ignition systems, battery powered in two stroke engines. My experience with them comes from their being used in the original 1969 thru 1971 Kawasaki H1 500cc two stroke triple cylinder motorcycle street bike engines. The last time I saw these plugs, was in one of those ads that pop up when you are on some sales site, for one of the online speed shops, about 10 months ago, touting them as THE answer to all spark plug problems...in YOUR, and MY auto engine.
It really doesn't take much these days to take something that is going its correct way, and derail it so far off track, it really isn't funny, by a very small bit of misinformation, intentional, or, not.
