Yeah, I think his 3 engine series articles are a must read for anybody 
flying today.

Assuming they are clean to begin with, how clean do they run?  I'd imagine

I'm running auto plugs on the EI, I can't remember the part no but they are 
the standard(cheapo) plugs that Klaus sends with the unit and 
recommends.   I bought a set of the high priced ones ($9.00 whole dollars 
apiece!)  and ran them for about 10 hours. I thought the cheapos ran 
better, so I switched back to them.  I change them every 100 hours, $3 a 
piece.  The EI plugs run a light tan color and are always as clean as when 
I took them out of the box.

The lower plugs, aviation type, on the mag get oily (my engine was broken 
in by an amateur and will probably burn more oil than it needs too until I 
rebuild the cylinders.  These lower plugs are the ones I need to clean 
every 50 hours.  If they get real oily I can't run any leaner than 50 LOP, 
or they start to misfire I guess.

I've heard good and bad about the ceramic coating, the bad being that it 
flakes off, especially on the inside.  I know of a couple high end exhaust 
shops that don't do it anymore unless the customer(always right) demands it.
