Lambda Sensor Adapter Reducer M18x1.5-M12x1.25

Lambda Sensor Adapter Reducer M18x1.5 to M12x1.25 TurboWorks – Thread Conversion for Smaller Sensors

What is a lambda sensor thread reducer used for?

The TurboWorks M18x1.5 to M12x1.25 lambda sensor adapter is a high-quality thread reducer that allows you to install a lambda sensor with a M12x1.25 thread into an existing M18x1.5 bung or port. It’s the perfect solution for engine swaps, sensor upgrades, or custom exhaust projects.

Technical specifications:

• External thread: M18x1.5 (fits most standard lambda sensor ports)
• Internal thread: M12x1.25 (for smaller-sized sensors)
• Material: high-grade steel
• Brand: TurboWorks

Applications of the reducer adapter:

This adapter is especially useful when:

• you have a sensor with M12x1.25 thread, but the port is M18x1.5,
• you want to install an AFR, EGT, or another small sensor,
• you are building a custom exhaust or turbo manifold,
• you need a clean, no-weld solution for sensor fitment.

Advantages of the TurboWorks adapter:

• Precision-machined for a tight, leak-free fit
• No need to modify or weld a new sensor bung
• Universal fit for various types of sensors and applications
• Quick and easy installation with standard tools

Summary – Lambda Sensor Thread Reducer M18x1.5 to M12x1.25

The TurboWorks M18x1.5 to M12x1.25 lambda sensor adapter is a practical and reliable solution for using smaller threaded sensors in standard M18x1.5 ports. A must-have for tuning setups, engine conversions, and motorsport applications.
