let me start off by saying, I'm not expecting any special performance boosts from spark plugs. I am confused why platinum plugs are not good for my m103 engine. I have used the Bosch 4+ plugs in my engine for about 10K miles.( I purchased these plugs before I knew they were bad) they haven't eroded the electrodes or caused any side effects. why are they no good in my engine. if someone could clarify this for me I would be grateful.
thanks,
Adam
