What is a W7DSR Bosch plug?
I pulled these out last week and was wondering what the difference is between the stock W7DTC plug?
Anyone know what the letters on Bosch plugs mean?

Do multi-electrode plugs run better?
It is/was my understanding that multi-electrode plugs are just for longer plug life, do to decreased electrode wear.
More electrode = less wear.
More electrode = less wear.
