B48 B58 S58 Charge Pipe Sensor Adapter Harness

Plug and play charge pipe pressure sensor adapter harness for BMW B48, B58, and S58 engines designed for use with AEM 5, 6, or 7 BAR boost sensors.

The B48 B58 S58 Charge Pipe Sensor Adapter Harness allows you to replace the factory 4 BAR charge pipe pressure sensor with a higher range 5, 6, or 7 BAR AEM pressure sensor without cutting or modifying factory wiring.

The factory sensor is a 4 BAR pressure sensor mounted in the charge pipe and used by the ECU for load calculation, boost control, and fueling modeling. When operating beyond the factory pressure range, a higher BAR sensor is required to prevent sensor saturation and maintain accurate pressure reporting.

This adapter connects directly to the OEM charge pipe harness and properly adapts it for use with AEM high pressure sensors.
