Key Features & Benefits – O2 sensor spacer 90 degree adapter with mini catalyst M18x1.5
The O2 sensor spacer 90 degree adapter with mini catalyst M18x1.5 is a 90° relocation spacer that helps reposition the sensor more cleanly within an exhaust system. For functional compatibility, it is intended for an M18x1.5 threaded exhaust bung and an M18x1.5 threaded O2 sensor.
The integrated mini catalyst supports filtering of harmful components, while the 90° layout helps placement where straight spacers are harder to package. It is made from stainless steel, and the thread fit is intended to support a tight, stable connection.
When is this useful?
This is useful when sensor placement is limited by space and a 90° sensor position improves clearance, while you also want the integrated mini-catalyst style design inside the exhaust system.

Selection & installation tips
- Verify threads: confirm both the exhaust bung and the sensor are M18x1.5.
- Check 90° clearance: test the rotated sensor position so the body and connector do not contact heat shields or bodywork.
- Seating & sealing: install on clean, burr-free mating faces so the threaded joint seats properly.
- Tool access: plan wrench access for tightening and future removal before final assembly.
- Harness routing: ensure the wiring is not under tension and stays away from hot surfaces in the new position.
Before installation, compare your M18x1.5 thread interface, available clearance for a 90° sensor position, and harness routing to the technical specs listed above.
