Bosch Oxygen Sensor P/N:16473
Bosch 13723 oxygen sensor for the 1995-1997 Porsche 911 H6 3.6L sends air-fuel-ratio readings to the ECU. This downstream Bosch O2 sensor helps reduce emissions across a wide range of operating conditions.
A failing oxygen sensor can show up as a check engine light, rougher running or poorer fuel economy. Before you replace this one, rule out exhaust leaks and damaged wiring or connectors, because those can also set fault codes.
This sensor fits the 1995-1997 Porsche 911 H6 3.6L and the 1999 911 H6 3.4L. These cars take two downstream sensors, and this listing is one sensor.
