Bosch CIS injector numbers and substitutes
I hope Tony will pick up on this thread:
My car has some irregularity at idle and hesitation/surging at cruise. It runs smoothly at wide throttle settings. I tend to think this is due to poor fuel atomization, so I'm considering changing the injectors.
I'm seeing a range of pricing on the same Bosch part number, 0437 502 004, from $36 on up to $70 or so. Other numbers associated with this injector include: 028851079518, 3165142315812, 62281, 911 110 225 01, 911-110-225-01, 911-110-225-01-M14, 911.110.225.01, 91111022501
I also saw a different part number for Mercedes, 0437 502 047, set of 6 for $132. Those were listed for a variety of MB engines, but with similar size cylinder displacements. If they are physically compatible, those should work too.
Has anyone tried different injectors in their Porsche CIS engines? Are there compatible injectors for MB, BMW, VW, etc. that work well and cost less?
