notes: While Type 4s (411/412)
and late Buses technically ran the same engine, the Type 4 had
different pistons so it would have higher compression which
necessitated a slightly cooler plug. This is not original but will
work in a late Bus if you would like to have a cooler heat range
on your spark plugs.
Bosch
discontinued the original WR7CC Super spark plugs and has
superseded them to the new Super Plus spark plugs. These are
simply a better plug with a longer life - otherwise they fit and
look just like the original style.
