If you use the standard Super W7cc, they do go fast in those motors. If you
use the stock W7CCO, the give at least 20,000 miles in a spec motor. That's
why they're special, which is what the last O stands for. In this case,
three electrodes. Not all last O plugs have three electrode, but they all
have specific unique features required by design. All the last O plugs are
more spendy 'cause they are, relatively speaking, produced in much smaller
volume for limited applications.
