Improve engine efficiency performance and fuel economy. Reduce CO2 and other harmful emission.The oxygen sensor, also known as air fuel ratio sensor, is an essential sensor for your car’s performance. The sensor is located in the exhaust system and helps with emissions control by allowing the fuel injection and engine timing to operate effectively.The sensor ensures that your car is driven with the optimal air-fuel ratio at all times, which helps extend the life of the catalytic converter.The oxygen sensor directly replaces the old parts and is easy to install.Easy to install, exquisite and highly compatible.Made of high-quality materials, with a long service life.Fuel saving, smooth refueling, solving hill climbing difficulties, and improving power systemNitrogen and oxygen sensors monitor the oxygen content in the engine's combustion chamber and help the engine control system understand the status of the combustion process in real time.Based on the feedback from the nitrogen and oxygen sensors, the engine control unit can adjust the fuel and air mixing ratio in real time to ensure optimal combustion efficiency.By monitoring and regulating the oxygen content during engine combustion, nitrogen and oxygen sensors help to reduce emissions of gases in exhaust gases and meet environmental standards.Optimizing the fuel-to-air mix ratio can improve combustion efficiency, which in turn improves the fuel economy of the vehicle.By adjusting the fuel and air mix ratio in real time, the nitrogen oxygen sensor maximizes the engine's potential and increases power output.
