I have to assume that the VW engineers picked plugs with a certain reach as
appropriate for the engine (1.9). Were longer reach plugs, such as the "D"
ones, available at the time?

W/r/t the risk of increased ping caused by plugs firing closer to the top of
the pistons, couldn't one compensate by using higher-octane fuel?

Not that I'm a great big fan of buying even more expensive gasoline, but I
do like the peppiness these plugs provide.
