O2 Oxygen Sensor; Downstream (04-08 F-150)Find parts that fit my vehicle

Continuous Exhaust Gas Analysis. The primary and indispensable function of the O2 Oxygen Sensor is the continuous and precise monitoring of the oxygen content present within the exhaust gases as they exit the catalytic converter. This real-time data acquisition is absolutely critical for the vehicle's Engine Control Unit (ECU). The ECU relies on this information to assess whether the catalytic converter is operating at its optimal efficiency in neutralizing harmful emissions.

Optimizing Combustion and Economy. By diligently providing accurate and up-to-the-second feedback regarding the post-catalytic converter exhaust gases, the O2 Oxygen Sensor plays a pivotal role in enabling the ECU to meticulously fine-tune the delicate balance of the air-fuel mixture within the engine. This precise adjustment, informed by the sensor's readings, leads to a more complete and efficient combustion process.

Environmental Stewardship. A properly functioning downstream O2 Oxygen Sensor is absolutely essential for guaranteeing that the catalytic converter is performing its crucial task of effectively reducing the levels of harmful pollutants present in the vehicle's exhaust gases. The sensor's constant monitoring of the gases exiting the converter allows the ECU to verify its effectiveness.

Installation. Putting this O2 Oxygen Sensor on your F-150 takes 1 hour to install.

Application. The O2 Oxygen Sensor fits 2004-2008 F-150 models.
