Now the modern cars like Porsche have oxygen or O2 sensor which is involved in the combustion process and plays an important role in enhancing their performance. Moreover, the O2 sensor is measuring the amount of unburned oxygen in the exhaust and conveys this information to the engine's computer for modifying the air and fuel intake.
