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 Image Unavailable, Please Login Image Unavailable, Please Login
4 are the old steel. 4 are the replacement brass. That is why the different number. Injector nozzles are not why your manifold is glowing.
