The differential pressure sensor is a vitally important component for the Particulate Filter which measures before and after the passage of exhaust gases through the filter and allows you to measure how clogged the particulate filter is.

Our "Sensor Compasses Set" includes 7 compasses of the most common sizes specifically designed and tested to be used on any car and in any circumstances you find yourself in front of.

Since most of the exhaust differential pressure sensor tubes have the disassembly fitting positioned on the bend of the tube, our set gives us the possibility of being able to insert the measuring bush extremely easily and to be able to orient it in the most suitable position for the situation with the possibility of using either the classic open-ended combination wrench or transforming it into a 3/8 mini socket by inserting the supplied wrench.
