What is the role of the oxygen sensor in the performance of your Hyundai Elantra? An oxygen sensor is an important part of your car’s exhaust system. This small sensor is used to detect the quantity of oxygen left in an exhaust gas during combustion process. It sends the reading to the electronic control unit or ECU to allow it to manage the proper combustion operation inside the engine. To let it perform its job properly, it is located on the intake manifold of your car. The Bosch Oxygen Sensor is the perfect replacement for the stock O2 Sensor of your Hyundai Elantra 1998-1998. This product detects whether fuel mixture inside the engine is rich or lean. Bosch is one of the leading developers of oxygen sensor technology and known for the durability and long life of their products. It is quite easy to fit the BS13367 Bosch Oxygen Sensor in your ride. All you have to do is to screw it in place on the exhaust pipe and use either one or two wires to secure it properly. To preserve the quality and efficiency of your oxygen sensor, you must avoid using unleaded fuel and prevent harmful particles such as silicone from penetrating it. Silicone can contaminate the O2 sensor and damage the catalytic converter of your car.
