I bought a set of CR9EK plugs (dual ground) going by memory from some of the threads that I have read here and noticed that the stock plugs are CR9E (single ground). I'm not looking to improve performance by going to the CR10Es or anything but what difference, if any, is there between the single and dual ground plugs?

Okay, I know somebody out there has an answer. Are the dual grounds just a marketing thing because the current will take path of least resistance anyway.

There are plugs with 4 ground electrodes. More ground electrodes less wear, longer plug life. Has nothing to do with performance. Secondary is cold start fouling is reduced.
