Whatever you do, dont use the bosche platinum +4...i made that mistake and had to correct it about 3k miles later. Im not sure about the 4 cylinder engines, but the 3.4 seems to be just fine with AC Delco platinums. I have had them for about 15k miles and they work great. Correct me if im wrong, but i think the AC Delco platinums are factory equipment.
