Why you need this tool?
- Cars usually are equipped with Two O2 Sensors.
- One is located on the exhaust manifold for regulating fuel supply, and the other is located downstream from the catalytic converter for measuring the efficiency of the catalytic converter.
- Due to the fact that the latter O2 Sensor is located on the exhaust pipe, it gets rusty and damaged easily as time goes by.
- The rusts lead the O2 Sensor to stuck or seize on the exhaust pipe and make it very hard to remove the O2 Sensor.
- So this is why you need this Air Hammer Powered Tool to remover the O2 Sensor easily!!
