99 323i works fantastic

My maf sensor for my 99 323i sedan went bad and considering the alternatives (OEM $500 and VDO Siemens $200) i opted to buy this 38 dollar unit to save a considerable amount of money. My car was throwing a P0101 CEL and this new unit fixed all my running issues. Put at least 1k miles on the unit so far and car runs fantastic. Thanks 1A Auto for fast shipping as well.
