[Note] 2018 and newer models require a service manual for DIY installation.
For DIY installation, you need to remove the O2 sensor from the base of the exhaust pipe from the cabrau side, otherwise you will never be able to install it.
The O2 sensor on the side of the exhaust pipe interferes with the engine guard mounting bolt, so it can never be removed.
If you try to remove the O2 sensor from the exhaust pipe side, the wiring may rotate rapidly and the screw may break.
Therefore, before loosening the nut of the O2 sensor on the exhaust pipe side, I first disconnected the coupler connected to the steering head side.
This is narrow and hard and quite difficult to remove without the Service Manual.
(The supplied manufacturer's instructions also state that the service manual should be consulted for removal of the O2 sensor.)
It is probably the Engine Guard of the Spec. when there was no O2 Sensor before 2016.
Honestly, I recommend that you buy it at a shop and have Mechanic install it.
If the O2 Sensor WiringScrew is cut, it may cause an error at the OBD and the engine may not start...
