i shudder to think. bosch motorsport, or so i have been told, dont actually want lots of these injectors around the place. the price is simply to put people off buying them. they were not that forthcoming producing them, after 6 months correspondence they took the order and then 12 weeks later they showed up, with no map, or suggestion of where to start. weve sussed it now but its been hard work. there are 2 sets in the uk that i know of, someone might be able to tell us different???
