I believe the map sensor was just mounted on this bracket, trouble is the failed due to orientation of sensor and were replaced as a recall. I have an rs500 bracket but it’s different to the 3 door one, can’t get pictures at moment, it is an aluminium bracket as per your picture but has a steel bracket bolted to it so map sensor is horizontal. My original 3 door bracket was just a rough fabricated steel bracket bolted to inner wing which I presume is the recall mod.
