Facet Engine Oil Pressure Switch 7.0072 Compatible with PORSCHE #OEM 91160623000-91161357101

All internal parts and components of the engine are lubricated through a network of conduits and ducts, in which oil is pumped at high pressure through a pump. Passing through the ducts and due to centrifugal force, the oil reaches all parts that need to be lubricated: camshafts, valves, rocker arms, bearings, connecting rods, cylinders and pistons. The lubricating oil is located inside the sump, from which it is drawn through the pump. These switches, activated by the pressure of the lubricating oil used in engines, serve to indicate to the driver, by means of a LED on the control panel, when the pressure of the lubrication circuit is insufficient compared with the prescribed value.
