I can accept that.  The only 20vt engines I service are a couple of S4s, 
and they are both newly purchased, so I have no data base from which to 
judge.  I am NOT a fan of the 60K intervals because of potential seizure 
to the head.  R&R of the plugs at intervals smaller than that requires a 
new gasket, and that becomes a largish PITA.  John
