Roger Galvin and I are experimenting at present with 1-prong plugs in
my MB and his 1B.  Both of us strongly suspect that the purpose of the
3-prong design is simply to extend the life to meet the service
interval Audi recommends.  We're currently trying to see if changing
1-prong plugs on a 2500-mile basis is better or worse than changing
3-prongers on a 7500-mile basis.

The jury's only just gone out.
