Paul [Yaw], I don't recall from memory, but they are the single electrode
plugs that MazdaTrix carries.  I will pull the plugs on this weekend
just to see if they could have been the problem and will let you know.

Hey Ed,

They are probably NGK B9EGV.  These plugs have the ground strap that
comes up and over the top of the center electrode.  Because of this,
they don't offer any performance advantage over the BUR-EQ type.  In
addition to the ground strap configuration, they don't reach as far into
the housing as the stock plugs.  In spite of this, they seem to work OK,
but they will not last as long as the BUR-EQ type.  The only advantage
is that they are non resistor plugs, which probably helps to offset the
other disadvantages.

I am currently trying to make some valid heat range, and horsepower
comparisons with other types of plugs in a high load situation.  When I
finally get the answers, I will let everyone know.
