The plugs I like to use are Autolite Platinums (pause while some folks click
the delete key because of anti-American sentiment).  Autolite makes a really
good platinum plug, they are a little more expensive than the Bosch plugs but
I have had really good experiences with them.  You can get them at any local
parts place.  If I was going to go Bosch I would either go with the Supers
(copper core) or maybe that new plus 4 platinum plug since it is supposed to
have a bigger center electrode.
That's my 2 cents.
