LF Front oxygen sensor.

Its not called an 02 sensor. The car has one 02 sensor and one Afr sensor. The 02 is in the downpipe and the Afr sensor "wideband sensor" is in the manifold collector before the up-pipe. If you still have the factory manifold heatshields then I suggest you get a dremel as the heat shield will need to be cut out before the Afr sensor is removed. Buy an 02 socket, dont use pliers on it.
