facts
when i got the car i began to search for advice and learned somewhere that it was convenient to replace the sensors, as there is no way to measure the wear, so i ordered these specific as advised (also, that had to be bosch).
but dont remember who, neither where i got them. and when i replaced them, the 1s that were before happened to be exactly the same part number (and of course bosch). but neither i know since when the car has been using these.
at the end of the day, the fact is that these work. the car runs as smooth as silk.
