Parts guy is wrong. NA model spark plugs last 100K. N54 or N55 plugs should be changed at 45K miles. And if your car has a tune change them every 30K like BMW says to on the 1M's.
I would say only use BMW bought plugs. There are cheaper sources around. I would hit up
Jason@Ticher or
Dan@United. Both can beat that $26 price. And don't forget to order a spark plug socket tool - since its a odd ball size plug(12mm, 12point edges).
PS: to be sure of your ECL I would first read your car's fault memory. Also if your car is still under warranty BMW will pay to replace your spark plugs.
