Lamda thread size
 

Does anyone know whether the blanking plug above number 3 cylinder is the same size thread as the lamda sensor? as im looking to use it to blank an extra boss i have in my exhaust

Not sure but i used a spark plug once they are the same size when i could not find a blanking plug.
