Yep, Ricky is correct. The CIS-E injectors have M12x1.5 threads, and
the Motronic injectors are M10x1 threads.
The visible difference is the CIS-E lines are flexible and have a
braided stainless jacket, and the Motronic lines
are a combination of black hard lines and rubber fuel line. I
*think* the fuel distributor ends of the injector lines
are the same (banjo fittings) for botth CIS-E and Motronic, so you
could use either fuel distributor with either
injector/line combination. However, the FPR and cold start valves
are specific to CIS-E or Motronic, so it's not
totally mix and match. So, I think you should run all the same
hardware as whichever ECU/fuel distributor
you're planning on using, Motronic or CIS-E. BTW, the injector
inserts are the same for both systems, so
either type injector will at lest screw in to the intake manifold.

What differences are between Motronic and cis-e injectors? Which
should I use in a 9A w/stock cis-e? I have 4 of each.
Thanks.
