I have been using Bosch W7DTC for years and found them to be the best overall plug for the 1.9 & 2.1 engines, longest lasting and never a problem.  Now Bosch has seen fit to discontinue that plug and my supplier is sending me Bosch WR7CC.  I have not used them in MY van as yet because my last set of W7DTCs are still working and looking just fine.  All my customers are now getting the WR7CCs and so far no complaints or problems.
