dont put bosch sensors in.
Chances are that brand new they wont be as good as your worn out OEM sensors.
ONLY motorcraft 02's!!!!
The bosch sensors are sluggish and slow to switch when they are brand new.
I put 1 in one of my cars and in the datalog it was worse than the sensor I removed.
I swapped sides and the goofyness swapped sides with the sensor.
TRUST ME TONY.. please
