I am looking to install an O2 sensor in to the exhaust system and I have a few questions for those that are in the know.

My current intention is to drill a hole into the current exhaust pipe after all the branches have met and to weld the correct sized nut over the hole so that I can screw in the sensor. Do I need to consider how far from the manifold I need to install the sensor or anything like that?

The intention is to get the sensor mounted at close the the "12 O'clock" position to minimise the chances of water accumulating on the sensor and causing damage.

I am also intending to mount it within the engine bay to avoid any complications with the IVA and protruding wiring etc. However I have seen other mount it just before the rear silencer, so I am not sure if I am missing something?

All thoughts welcome :D

Cheers,

Jon

Hi Jon

I can't give you an exact answer as to where an O2 sensor is best placed.

For what it's worth, the vast malority of cars that I have worked on have the O2 sensor reasonably close to the manifold.
Usually just below where the manifold pipes join into a single pipe ( More or less, as you described )

You should be able to get a suitable weld in boss on ebay.
O2 sensors standard thread size is: M18 X 1.5 thread pitch.

Hope that is of some help. :)
