After putting a new set of spark plugs
in the family limo yesterday, the
thought struck me that I had mindlessly
put some little bushings (washers,
whatever??) that came with the plugs
on each plug.  I've been doing the
same thing for several years now that
I think of it without ever having
realized that way back when plugs
didn't come with those bushings.
What really got me thinking was the
fact that I had to install the bushing
on each plug so maybe the bushings use 
is optional.  I would imagine if this
is so, the bushing is a way of making
the plug "colder".  Anyone really
know what those bushings are for and
when they should be used?
