If a Bosch MAF insert is marked as a model XYZ, does the panel think all new Bosch MAF's marked as an XYZ will be identically calibrated?
To put it another way...
If a Bosch XYZ insert fits housing A, B and C, will model XYZ be calibrated for A or B or C, or will it work as intended with all of them?
The thing is, we may have found a source of XYZ, in a different housing, which is around one third the cost, for a genuine Bosch MAF insert.
