Awhile back Denis recommended these plugs: Bosch 4477.  Upon this recommendation I ordered some from my Bosch supplier.  They arrived yesterday and I now see these are the Bosch Platinum with four tips.  Now, here's my question, anyone have any real life experience with these plugs in the 1.9 and 2.1 waterboxer engines ?  I seem to recall having bad experience with them here.  Seems to me the ignition system on the waterboxer engined Vanagon's is not powerful enough to fire these plugs correctly.  Am I just dreaming or what ?

Cheers,
