Lambda probe extends 0 degree - (M18x1.5) - With mini catalyst

Lambda Sensor Extender 0 Degree – M18x1.5 – with Mini Catalytic Converter

0 degree lambda sensor extender with integrated mini catalytic converter and M18x1.5 thread for installation between the exhaust and the lambda sensor. This type is typically used on the rear lambda sensor, where the aim is to move the sensor slightly away from the direct exhaust flow while also allowing a smaller portion of the exhaust gas to pass through a small catalytic insert inside the extender. The mini catalytic converter version is often described as a more effective solution than a standard empty spacer, because the sensor is not only moved, but also exposed to a more damped reading.

The straight 0° design makes it suitable where there is space for a straight installation, and M18x1.5 is the standard thread size used on many lambda and O2 sensor applications. This type is typically used as a universal solution for the secondary or rear lambda sensor after the catalytic converter.

Experience shows that this type can in some cases work better than a standard extender, but the result still varies greatly from vehicle to vehicle. On some vehicles it may be enough to reduce or avoid catalyst-related fault codes, while on others it will not solve the issue. If there is a real fault in the catalytic converter, lambda sensor, or exhaust system, an extender is not necessarily the solution.

We have sold many of this type to business customers, where some buy larger quantities at a time and come back again. That says a lot about it being a popular and in-demand solution for workshops and professionals working with exhaust systems, diagnostics, and special builds.

Please note: Performance and function depend on the vehicle, software, engine management, and the specific cause of the fault. This product should therefore be regarded as a component for testing, motorsport, and special builds where sensor signal and sensor position adjustment are part of the setup. Results cannot be guaranteed in all cases.
