I was told this rule of thumb by a very good mechanic many many years ago...

For American cars, buy american plugs...Motorcraft, AC Delco, etc
For Japanese cars buy Jap plugs...NGK, Nippondenso, etc
For European cars buy european plugs, Bosche, umm...more Bosche

Ive probably owned twice as many vehicles as most of you are in years (well over 40 last time I counted), and Ive always followed this rule of thumb and it has always worked for me...
