Cars are one of the contributors of harmful gases to the environment. It is for this simple reason that your Hyundai Sonata is fitted with an oxygen sensor. This electrical sensor is installed in the intake manifold of the exhaust system to read the amount of remaining oxygen present in the exhaust gas during engine combustion. After measuring the oxygen level, it sends the information to the electronic control unit (ECU) of the car to enable it to do the proper combustion procedure. For better performance and efficiency, replace the stock oxygen sensor in your vehicle with a Bosch Oxygen Sensor. The ability of your engine to generate power depends on the richness or leanness of the fuel mixture during combustion. The Hyundai Oxygen Sensor by Bosch BS13748 is crafted from high-grade materials that have the ability to withstand extreme temperature for a longer life. Owners of 1999-2001 Hyundai Sonata will greatly benefit from this premium oxygen sensor that is very easy to install. It only takes a few screws and some wires to fit it in place. However, you must still take proper care of the oxygen sensor in your car. You can do this by not using unleaded fuel which contains harmful particles that could damage the O2 sensor.
