Did the trick.
With the engine warning light coming on periodically, (following an OBD2 scan) it became clear that I was having problems with my catalytic converter. After fitting this device to the downstream O2 sensor the engine warning light stayed off, (and with the use of a catalytic cleaner) allowed me to pass the MoT test. Well worth the money !

Worked a treat!
Worked a treat on my 2025 MT-07 when de-catting the exhaust system fitting an Akrapovic.

Well made, good quality.
This oxygen sensor extender seems well made, strong, with good clean threads and no sharp edges or burrs from manufactiring. I haven't actually installed this yet but they work by removing the downstream oxygen sensor from the flow of gasses therefore causing the sensor to have a decreased reading and fooling the ECU into thinking all is good with the emissions control system and turning off the emissions light. A handy temporary measure if needed to get the engine light off on your dash until you get the problem fixed.
