Key Features & Benefits – O2 sensor spacer straight adapter with mini catalyst M18x1.5
The O2 sensor spacer straight adapter with mini catalyst M18x1.5 is a straight O2 sensor spacer with an integrated mini catalyst, described to reduce harmful content in exhaust gases and optimize O2 sensor operation. For functional compatibility, it is intended for an M18x1.5 exhaust bung and an M18x1.5 threaded sensor.
Made from steel, the compact shape can be easier to use where space is limited and a straight outward position is possible. The M18x1.5 threads allow simple connection to an existing setup when the thread standard and seating style match.
When is this useful?
This is useful when you want to relocate an O2 sensor at an existing M18x1.5 threaded point using a straight adapter and you specifically need the integrated mini-catalyst style design within the exhaust system.
Technical specs
- Thread size: M18x1.5
- Material: steel
- Design: straight adapter with integrated mini catalyst
- Compatibility: described as compatible with most vehicles using M18x1.5 O2 sensors
Selection & installation tips
- Verify threads: confirm both the exhaust bung and the sensor are truly M18x1.5.
- Check clearance: make sure the adapter and sensor can sit in a straight position without contacting heat shields or bodywork.
- Seating & sealing: install on clean, burr-free mating surfaces so the joint seats properly and avoids leaks.
- Tool access: plan wrench access for tightening and later removal before final assembly.
- Harness routing: confirm the connector and wiring are not under tension in the new position and stay away from hot surfaces.
Before installation, compare your M18x1.5 thread interface, available clearance for a straight sensor position, and the seating style of your mounting point to the technical specs listed above.
