Key Features & Benefits – O2 sensor spacer straight adapter with filter M18x1.5 47 mm
The O2 sensor spacer straight adapter with filter M18x1.5 47 mm is a relocation piece that positions the sensor further out from the threaded bung, helping reduce direct exposure to the exhaust gas stream and deposits. Built with a stainless steel body and an integrated filter, it suits clean, straightforward exhaust installs.
With M18x1.5 male/female threads, it is intended for exhaust bungs and sensors that use the same M18x1.5 thread standard. The specified 47 mm extension helps when you want the sensor to sit slightly further from the main flow within the available mounting point.
When is this useful?
This can be useful on modified exhaust setups where you want the sensor positioned a bit further from the main gas stream and you need a simple, space-aware way to relocate it at the existing threaded location.

Selection & installation tips
- Thread & sealing style: confirm both the exhaust bung and your sensor are M18x1.5, and check the seating/facing style used on your setup.
- Clearance check: a 47 mm extension needs enough space around the sensor, so measure against bodywork, heat shields and drivetrain parts.
- Harness routing: make sure the connector and cable are not under tension after the sensor is moved outward.
- Correct orientation: point the filtered end toward the exhaust stream and screw the sensor into the adapter’s female thread.
- Clean install: use clean threads, ensure proper seating, and follow vehicle/sensor guidance for tightening and thread care.
Before fitting, self-verify the M18x1.5 threads, the 47 mm extension clearance and the harness reach on your vehicle, then compare your mounting point and sensor interface to the technical specs listed above.
