I just did this today. Replaced plugs for Platinum +4 Cap & Rotor
,and wires. My old plugs were also the regular vanilla bosch.  My plugs
were not brown but had black around the base of the thread and I believe
the gap was wider than the spec .07  An additional question I have is that
after replacing cap & rotor, my cap seems to dance (wobble) a lot when the
engine is on.  Just wondering If I missed something when installing the
new cap & rotor.
