I am trying to get a hold of a maf to try and see exectly if mine is wrong or not but was checking on a site onlinecarparts.co.uk and found some mafs etc in it but not oem some brands like vemo vaico hella etc and was wondering if any of these are any good they are not that cheap but they are cheaper than oem for sure.I know the oem lambda sensor is made from bosch so thats not a problem but i would like to know what brand makes the oem mafs
