Oxygen sensors
 

Hey guys just exactally how many oxygen sensors does a bugeye wrx have. My diagnostic only reads two but don't know if that is right???????

yes mate it has 2, one is up stream in the headers (this 1 is for air/fuel mix) and one down stream after the down pipe this measure cat efficiency

should only be the two, pre cat & post cat...

cheers guys
