afternoon I'm in the process of changing all 8 injectors on my car and find out, pulling the injectors, that bank 1 injectors were probably change at some point. Injectors are Bosch 0 437 502 047 and bank 2 as injectors labelled 0 407 502 010. Find attached pictures of both banks injectors. Of course I've ordered 047 version from AutohausAZ. The funny thing is that bank 1 headers are glowing red, and the injectors are looking in much better shape than bank 2. bank 1 : closer to the trunk. Could the number on the injectors have change over the last 30 years ? Thanks Marc-André 80 308i
just for clarification... rear bank: closest to trunk front bank: closest to the passenger compartment if you have a complete set of new injectors, change them all if your headers glow on one bank, check timing on that bank (put cyl. 1 on tdc, check tdc mark on flywheel and see if all 4 cams point to their correponding marks)... chances are, that the bank in question ist out of time...been there... good luck edit: just saw that you posted the same question yesterday and it was already answered
CIS ALL use the same no0zzle save the "shorties" used by BMW for 320i and such.. All Ke, or fine threads., are the same for ALL Ke ..thus, all you need is a set of brass jacketed-steel NLA- coarse, CIS nozzles, and insatalled in no particular order, remeber to replace3 aLL seals....
