Do this injectors: Bosch 0 280 155 712 pass to e36 m42 motor?

at 3bar fuel pressure they'll be good for ~17.5lb/hr - double-check what the impedance is, a quick google didn't come up with anything for me

I want know do them pass physically to m42? They flow little bit more than stock injectors 190ccm vs 204 and both are four pinttle injectors and high ohm.

And yes, my problem is lean afr with Dbilas itbs and grinded intake-cam. I tryed S50b30 240ccm injectors but car doesnt work with them. It runs too rich and run very very bad, sound like 2-stroke motor and smell like fireworks.:mad:

I think i buy them (204ccm) and try if it works finally:cool:

They work on the E30 M42 but the E36 94+ has the stupid air shroud injectors.

I dont know why, but i dont have air shroud injectors and my car is e36 07\94. I have "normal" style injectors in my car, so they should fit:cool:

i'm surprised to hear that... i had to go all the way up to 24lb/hr injectors, with a slight bump in fuel pressure, to get my car to the 12.8:1ish AFR MarkD said was best for the M42.

As previously mentioned, they were also installed in 94+ M42s depending on which market you were in.
