Product Information

Full details

This adaptor is for motorcycle enthusiasts and tuners looking to upgrade their exhaust system with a wider range of Bosch Lambda (O2) sensors. It offers a key benefit of enabling the use of more accurate wideband sensors for precise engine tuning, but requires careful consideration of the angled fitment on some exhaust bosses. The adaptor features an M12 male thread to an M18 female thread, is constructed from durable stainless steel, and allows for rotational adjustment for optimal clearance.

FAQs

What type of sensor does this adaptor accept?

This adaptor converts an M12 male thread on the exhaust to an M18 female thread, accepting Bosch wideband Lambda (O2) sensors with an M18 male thread.

Do I need to buy a separate Lambda sensor?

Yes, this product is an adaptor only. You will need to purchase a compatible Bosch wideband Lambda (O2) sensor separately.

What is the angle of the adaptor?

The adaptor is angled at 45 degrees to provide extra clearance around the exhaust system.

Can I adjust the angle of the adaptor?

Yes, the adaptor can be rotated and locked off in any position after initial installation to achieve optimal clearance.

What material is the adaptor made from?

The adaptor is constructed from durable stainless steel.

Is a sealing washer included?

Yes, the adaptor is supplied with a copper sealing washer for the Lambda sensor.

Will this fit all motorcycles?

It is designed to fit the O/E motorcycle lambda exhaust boss with an M12 female thread. However, physical clearance for the angled fitting may vary between motorcycle models.

Troubleshooting

Adaptor does not fit exhaust boss.

Verify that your motorcycle's original Lambda sensor thread is M12 female. Ensure you are not cross-threading. Check for any debris or damage in the exhaust boss threads.

Difficulty achieving a good seal.

Ensure the copper sealing washer is used and properly seated between the sensor and the adaptor. Tighten the sensor to the adaptor firmly but do not overtighten, which could damage the threads. Verify the exhaust boss threads are clean and undamaged.

Exhaust leak detected around the adaptor.

Check that the adaptor is sufficiently tightened into the exhaust boss. Ensure the copper sealing washer for the sensor is in good condition and correctly installed. For persistent leaks, consider using a high-temperature exhaust sealant specifically designed for O2 sensor bungs.

Wideband sensor not reading correctly after installation.

Confirm the Bosch wideband sensor is compatible with the M18 female thread and has the correct type of connector for your tuning device. Ensure the sensor itself is functioning correctly and has been calibrated according to its manual. Check all electrical connections.

Pros and Cons

Pros

  • Allows for the use of more accurate wideband O2 sensors.
  • Provides better engine tuning capabilities.
  • Angled design helps with clearance issues on tight exhausts.
  • Rotatable fitting offers installation flexibility.
  • Constructed from high-quality stainless steel for durability.

Cons

  • May not fit all exhaust configurations due to the fixed 45-degree angle.
  • Requires the purchase of a separate Bosch wideband Lambda sensor.
  • Potential for exhaust leaks if not installed and sealed correctly.
  • The thread conversion might limit sensor options if an M18 sensor is not desired.

Setup, Compatibility & Care

Setup:

  1. Ensure the exhaust system has cooled down completely before installation.
  2. Remove the original M12 Lambda sensor from the exhaust boss.
  3. Clean the threads of the exhaust boss and the adaptor.
  4. Screw the M12 male end of the adaptor into the exhaust boss. Hand-tighten first to ensure proper thread engagement.
  5. Position the adaptor at the desired 45-degree angle for optimal clearance. Once positioned, tighten firmly using an appropriate wrench.
  6. Install the Bosch wideband Lambda sensor (M18 female thread) into the adaptor, using the provided copper sealing washer. Ensure the sensor is tightened according to its manufacturer's specifications.
  7. Connect the wideband sensor to your compatible tuning device or gauge.

Compatibility:

  • Sensor Thread: M18 Female (accepts Bosch wideband Lambda sensors with M18 male thread).
  • Exhaust Boss Thread: M12 Male (fits original equipment motorcycle Lambda exhaust bosses with M12 female thread).
  • Exhaust Type: Designed to fit into a standard M12 threaded exhaust boss on most motorcycles.

Care:

  • Periodically check the connection for tightness and signs of exhaust leakage.
  • Keep the exterior of the adaptor clean from dirt and debris.
  • Avoid using harsh chemicals or abrasive cleaners on the stainless steel.
  • Ensure the connected wideband sensor is also maintained according to its manufacturer's instructions.
