Hey all looks like the maf is shitting out and it’s time for a new one. Tried cleaning it today but I’m testing it later. In the case it’s shot, any good brands that won’t break the bank like oem or Bosch? I know sometimes oem prices are excessive for what they give you but is the maf one of those things that NEEDS to be oem?
The eBay and other copies are not recommended. Better to try a used one if the budget is tight. I’d say the hfm and cam sensor should be oem.
There is an OEM Siemens/VDO version that is less expensive than the BMW version.I have not used personally but the cost is less ($308).https://www.fcpeuro.com/products/bmw-fuel-injection-air-flow-meter-e36-e39-13621703275
The BMW version is $395 at GetBMWParts

Buy a used one for $50 from a 96-99 328i or M3.
Bosch, VDO, Siemens vs China Made copies:
Here's what I have heard from a Bosch electronic engineer when we discussed about the M70 MAF: the HLM (hot-wire MAF, among others also for M70) are repaired/remanufactured in a Goettingen/GER Bosch location. Here for the repair new platinum wires are installed. To my knowledge, this is not done in any outside workshops, but it is a Bosch-internal refurbishment process. I would advise against the cheap copies from eBay for 60, - € or so. Samples of these so-called "repro" parts we receive often in our quality department. The parts only look the same externally (even partly with Bosch lettering and part number). In most cases, the characteristics is far different from that output by a original Bosch MAF. In the best case, you "buy" a higher fuel consumption, in the worst case, it leads to further damage -for example, due to too lean mixture- of the engine.
