Hi, I want to order plugs for my "89 3.2. I intended getting platinums, but noted the comment that they are not going to perform well with the standard ignition system, owing to higher current draw. Yet, in the Ignition Tune Up article, Fig.1 photo shows bits for an SC older than my 3.2, and caption mentions "standard Bosch platinum plugs". Should I get platinums or iridiums??
