Description Reviews The MINI Supercharger Pressure Sensor Tube is the fix you need to fix the broken tube that goes from the map sensor on the side of the head to the supercharger intake ducting. Plastic only lasts so long in a hot engine bay. This tube helps read the pre-supercharger boost level to make sure the car can see pre and post supercharger boost levels. This tube breaks at the gray tube to the black base when working in that area. This is a MINI OEM part with a MINI warranty.
