Key Features & Benefits – Lambda sensor spacer 90 degree adapter M18x1.5
The Lambda sensor spacer 90 degree adapter M18x1.5 is a 90° angled threaded adapter designed to reposition a lambda (O2) sensor in an exhaust setup.
It is intended for M18x1.5 sensor and bung threads when you need improved clearance or more practical connector and harness routing around the sensor location.
When is this useful?
It helps when space is limited around the O2 sensor, or when rotating the sensor by 90° is needed to avoid interference with shields, bodywork, or nearby piping.
Technical specs
- Use: lambda (O2) sensor spacer / relocation adapter
- Design: 90°
- Thread: M18x1.5
Selection & installation tips
- Thread check: confirm both the exhaust bung and the lambda sensor use M18x1.5 threads.
- Clearance test: trial-fit the adapter and ensure the 90° angle still leaves room for the sensor body and connector.
- Harness routing: plan the cable path so it is not stretched and does not touch hot or moving components.
- Sealing: inspect the mating surfaces and use only the sealing method specified for your sensor/vehicle.
- Tightening: follow the tightening guidance for the sensor and threaded port, and avoid over-tightening.
Before installation, always verify the thread size, available clearance and harness routing, then compare them to the details listed above for a reliable fit.
