According to http://www.boschusa.com/AutoParts/PartFinder/partfinder.asp

I get this for my '88 2.1L

Part Number     Description             Where to Buy
4233            PLATINUM PART / MV; Gap=.030            Locate Retailer
WR7CP   PLATINUM PLUG / MV; Gap=.030            Locate Retailer
7598            SUPER PART / MV; Gap=.030               Locate Retailer
W7CC0   O.E. SPARK PLUG / MV; Gap=.030          Locate Retailer
W7CC            SUPER PLUG / MV; Gap=.030               Locate Retailer

It's not clear if the #4233 is a +4, but I suspect it is. I'm using the WR7CP now, which
has a single electrode.

FWIW, they list all the same plugs for the 1.9L engine, except with a gap of 0.028...
