Got a set m50 injectors and installed on my 12/89 325i over the weekend, unlike my last set from a different seller these worked flawlessly. I havent noticed any immediate change in performance though I'm blaming it on the adjustment period with the DME and I've only put on about 100km so far.
Shipping and communication was great, product exactly as advertised.
Tips and tricks for install on a stock m20, assuming late model is to be sure of a couple things
1: Depressurize as noted above
2: disconnect the electrical connectors and if you have the later style the twist lock under the intake
3: undo both fuel lines form the rail, leave the regulator in place. Drain any excess fuel into a small container
4: Unbolt the rail
5: Use a cloth to protect your valve cover and lightly pry the rail upwards and off the injectors with a large flathead screwdriver or prybar and pull it out from the front of the motor, might need to wiggle it a bit.
6: pull the injectors out of intake manifold
7: lube and install new injectors into the intake
8: reverse of removal.
