I just put Bosch Platinum in mine about a month ago. I went to get new spark plugs and Advance auto parts had the bosch platinum plugs on sale for what the copper plugs cost. So, I figured I would try it out. No messages or codes (other GEMA engines are using platinum or iridium from factory), runs fine, no increase in MPG or performance. Nothing magical happening here.
Use whatever spark plugs you want that are listed as compatible for your engine.
Will the platinum plugs last longer than the copper plugs? I guess I'll find out....
