Billet External MAP Sensor Adapter
Billet External MAP Sensor Adapter for BMW N5X / S5X Engines
A simple solution for converting from the factory plastic MAP sensor to an external MAP sensor setup.
This billet adapter replaces the factory MAP sensor and seals the original sensor port while providing a 1/8" NPT threaded outlet for routing an external pressure reference.
This is especially useful on standalone ECU installations where you want to use the ECU’s internal MAP sensor rather than retaining the factory BMW sensor.
Features
- Billet aluminum construction
- Direct replacement for the factory plastic MAP sensor
- 1/8" NPT threaded pressure port
- Allows use of a silicone/vacuum hose fitting of your choice
- Optional 4mm hardline adapter available - Ideal for use with MaxxECU internal MAP sensor connections
- Clean, compact solution for standalone ECU and motorsport installations
Optional 4mm Hardline Adapter
For installations using hardline, like MaxxECU Gen1 Internal sensors, select the optional hardline fitting. This setup is commonly used with MaxxECU installations, allowing a clean 4mm pressure line to be routed directly from the intake manifold to the ECU's internal MAP sensor.
Fitment
Fits many BMW N5X and S5X engines using the common factory-style MAP sensor mounting arrangement.
