I've used both on my '88 and '89 SPGs.
The common part number for the fr7dpx is 4201.
My experience was that the Bosch plugs didn't allow the car to have the same "punch" off the line as the NGK BCP7EV plugs. The gas mileage was slightly better with the Bosch plugs, but I had more fun driving with the NGKs in the car. Of course, that's probably the mileage suffered a bit with the NGKs.
The Bosch 7ES plugs will work equally well as the EVs.
