Bosch Oxygen Sensor P/N:16155
Bosch 13820 oxygen sensor for the 2002-2004 Ferrari 456 M GT and other vehicles reads the oxygen in the exhaust and reports the air-fuel ratio to the ECU. It is a downstream, narrow-band heated sensor that helps the ECU keep combustion stable and emissions down.
A slow-reacting or worn oxygen sensor can show up as a check engine light, a rough idle or poorer fuel economy. These signs alone do not prove the sensor is at fault, since an exhaust leak near it can skew the readings too.
Along with the 2002-2004 Ferrari 456 M GT, it fits the 2002-2004 Ferrari 456 M GTA and the 1997-2002 Ferrari 550 Maranello. If your Ferrari is not named here, enter it in the "Vehicles it fits" section to see whether this sensor is listed for it.
Fit and size
Build and materials
One oxygen sensor with its wiring harness; a mounting bracket is not included. This listing holds one sensor, and the Ferrari models named on this page take two.
Is the Bosch 13820 right for the 2002-2004 Ferrari 456 M GTA?
Yes. The Bosch 13820 oxygen sensor fits the 2002-2004 Ferrari 456 M GTA, and it is a downstream sensor.
Does this Bosch O2 sensor come with a wiring harness?
Yes, the Bosch 13820 comes with its wiring harness. A mounting bracket is not included.
What thread and hex size does this Bosch premium oxygen sensor have?
This narrow-band heated sensor has an M18 - 1.5 thread and a 22 mm hex. Its length from the sealing surface to the end of the connector is 38.2 in.
How can I tell if a downstream oxygen sensor is wearing out?
A check engine light, poorer fuel economy or a rough idle can mean the sensor is wearing out. A shop can read the sensor's signal with a scan tool.
How quickly does the Bosch 13820 reach operating temperature?
It reaches operating temperature in less than 10 seconds. That gives the ECU a quick signal for closed-loop control and better cold-start performance.
