So, as to not bring up a debate, is the general consensus that a good stock replacement for injectors the 0280150556 ? As they have the same fitment and flow? 22 pages of reading this took a bit of time, lol. I want to make sure I'm about to pay for what's needed in my car (1991 318is prod. 9/90)

Also, what/where is a recommended place to purchase as I've seen a few links but they all seem to be broken (except for the ones that end up getting debunked as too much, wrong size, retarded, etc.)

Thank in advance - need to go ahead and get some.

There's no general consensus and it depends on your power.

If you live near a Pick N Pull or other corporate-run junkyards, look at mid to late 1990s Fords, Saabs, Volvos and whatever else is listed through Bosch. You can often see the injector #'s or at least the general shape and color of the injectors without removing the intake manifold. Ex: 700, 710, 712, 715, 746, plus the 5xx and 9xx options already mentioned. Make sure you get the thin looking ones with grooves on the top half for the square clips. There are smooth ones without slots for the injector clips that won't work. Take 5 or 6 of each series you want and put them [in a bag] in your pocket and get them for free (fuck Pick N Pull, plus you already paid a few dollars to get in). After that you can either clean them yourself and go to an autoparts store to buy new o-rings (about $10-15 for all eight) and maybe buy some Lubro Moly Fuel Injector cleaner, or ship them out to be professionally cleaned and flow-rates tested. Or just buy them online to begin with.

Is there reasoning behind saying to get the skinny ones instead of the ones that match the factory look? Not siding either way, just wondering.

The fat ones like OEM are the old EV1 Bosch series still used in the early 90s with "150" in model #. Thinner ones = 4 hole EV6 with "155" in model #. Size of the injector doesn't matter as long as the o-rings on the top and bottom sit as well as stock. The length is almost identical, I think the 155's are ~1-2mm longer on top, and ~2-3mm shorter on bottom, but the actual nozzles are kind of hidden so it's hard to tell which sits lower.

That makes enough sense, lol - I thought the 0280150556 were 4 port/nozzle and that's why it was referenced has an 'upgraded/oe replacement'

So I'll be on the look out at a couple yards for those - thank you very much

Or - if I were to just order a new set - do you have a recommended part number? I see a new one up for xxx 156 xxx

Pretty sure that those will do. I have 0280150943, they are common and work good so far.

Also I have an e36 and someone told me that the newer m42 in the e36 already has a 4 hole nozzle, is this true? Also what kind of power gain would you get out of these injectors?

Yes the e39 m42 engine has The 4 hole injectors. They are Lucas brand.  The pintles are buried WAY inside the injector not right at the end like the bosch mustang injectors. I can post pictures if you want them. I am running the mustang injectors in my e36 m42. The idle is much better and the engine is smoother at all rpms. It seems to pull a little harder but I cant say there is any significant gain in power. I attribute the smoother idle and smoother running to a better injector spray pattern... Hope this helps...Skid

Can you post pictures of the injectors? How's the fuel consumption with mustang injectors?

skid,

thanks for the photos and info. I am about to ask mechanic to take out injectors to inspect. is it possible to clean or some special tools are required? I have constant  fuel starvation during acceleration resulting in momentary power loss or "diving" effect. I still do not know what the cause is. this happens at 2000 rpm onward and a bit of jerk. are clogged injectors the cause?

someone told me it could be the afm that doesn't open the flap properly like getting stuck. but usually at higher rpm, the flap should not get stuck. what's your experience?
