Fine Wire Iridium aviation spark plugs in
TSIO550?
Has anyone used the Fine Wire Iridium aviation spark plugs
(RHB32S) in their TSIO550?
Comments?

Iridium is a
precious metal that is 6 times harder and 8 times stronger
than
platinum, it
has a 1,200=F higher melting point than platinum and conducts electricity better. This makes
it possible to create the finest wire center electrode ever. Prior till now, Champion
has favored
platinum for
their long life or performance automotive spark plugs due to its high
melting point, also the technology did not exist to machine and bond
iridium on a spark plug electrode (at least in a cost effective
manner). Champion spark plugs has made iridium industrial and aviation
plugs since the 1960's, But advances in late model engine design have
necessitated the need for iridium in automotive applications. The
strength, hardness and high melting point of iridium allow Champion to
manufacture their iridium ultra-fine wire center electrode to 0.7mm. One of the finest
firing points in the industry! (Thus far there has been no problems
reported regarding use of iridium plugs with nitrous oxide.)
