Suitable for fitment to Toyota 4age 20v silvertop and blacktop motors.
These O2 sensors have mounting holes 54mm apart (centre to centre) and a non-removable flange, however may require some modification for some applications.
Do note some 4age 20v motors have slightly wider studs and in some cases slots may have to be cut into the flange for fitment. we have done this ourselves and fitted one to a car with no issue.
Description
The oxygen sensor is a device which determines the oxygen content of the exhaust gas. Since the amount of oxygen in the exhaust gas is a very good indicator of combustion efficiency it is also the best place to monitor the air fuel ratio. Located in the exhaust system the oxygen sensor produces a voltage proportional to the amount of oxygen in the exhaust versus the air (750 mV rich). This data is used to control the air-fuel mixture
