Thanks, Tom...I learn something every day. I thought dissimilar metals
might tend to corrode together.>>
They can. Actually, identical metals are much more likely to seize and bind,
which is why the Airhead exhaust threads are always a problem area, and
Stainless Steel fasteners MUST be coated with anti-seize before installing the
nut to the bolt, or the SS will definitely seize.
But spark plugs are not simple metal things. They are plated and coated
right from the factory. It is no secret to the engineers at Autolite and Bosch or
any other plug maker that the cylinder heads are aluminum. So they use
platings that will prevent this seizure. You do not need to second-guess their
research and testing.
Personally, I am not crazy about the plating used on Autolite plugs. They
always seem to be real rusty when I pull them out, at least the outer part of
the shell, not the threads. I just don't like rusty stuff on my bike.
Before you come back and post how great the Autolite plugs worked on your
bike, try a simple blind test. Get a pair of the Autolites, and a pair of NEW
Bosch or NGK (they specify both for different models) plugs for your bike from
BMW. Have a trusted friend install one set in your bike, and take the other
set home. Ask him to NOT tell you which plugs he installed. Ride the bike for
1000 miles, making notice of how it runs. Now ask your trusted friend to
swap the plug brands, still without telling you. Now write down your
observations of the power, smoothness, surgeing, etc., with each set of plugs. Now ask
your friend to tell you which plugs went with each observation.
You will discover what a lot of other guys have already discovered: NEW
plugs make the bike run noticeably better for a while. So does new oil. The brand
isn't very important, as long as you use the recommended specification, i.e.
heat range (plugs) or viscosity (oil).
Whenever I am feeling like my bike is running crappy, I feed it a fresh set
of plugs and a change of oil. Sometimes I discover that it was only 1500
miles ago when I last serviced the bike. Still makes it run nice for a trip.
