hi,
1982 635 csi, car has been sitting for 5 years, rather than paying to clean injectors should i just go out and buy new ones, if so what do i buy these days,
need brand and numbers?, injector technology today has to be better than it was 35 years ago!!, engine is still okay, my son thinks the exist. ones leak.
regards
richard

Re: injectors
Research Five-O-Motorsport - they are good to deal with.
I installed what they commonly call the "Mustang 19lb Injectors", for exactly the same reasoning you are asking. These have a 4-hole disc nozzle for better fuel atomisation and flow slightly more fuel. If running the standard AFM this will need slight adjustment to compensate, but otherwise with no other changes, noticeable improvement.
I think they are these: https://www.fiveomotorsport.com/bosch-y ... l-injector, as it is a while ago and they have changed the part no's, but look and sound the same.
Check the impedance of your injectors first (high or low), as others here will tell you. I was ignorant of this but had no issues.

Re: injectors
You will be able to run the newer "mustang" injectors with no issues.

Re: injectors
thanks for the info, where do i find out if they are high or low impedence, not to savvy with these things, i have a standard afm and if need be how do you adjust for the extra flow?,
best regards

Re the impedance, search "injector impedance" on here. I found this viewtopic.php?f=2&t=21528&p=152504&hili ... ce#p152504
Re the AFM adjustment, take the car to a service shop familiar with older BMW's, with an exhaust gas analyser.
