1. and sturdy: The car oxygen dryer has excellent high temperature resistance and wear resistance. Capable of adapting to harsh high temperature and high pressure environments in automotive systems, extending life, reducing replacement frequency, and lowering maintenance costs 2.Convenient installation: Equipped with the same interface and mounting bracket as the original car, no complex modifications are required. The upstream sensor of the car can be directly replaced with the old oxygen sensor of the original car, and the installation process is simple and fast 3.Stable performance: Upstream and downstream sensors of the car help the engine maintain precise airfuel ratio, allowing fuel to burn fully and effectively reducing fuel consumption. Long term use can save car owners considerable fuel costs 4.Fault warning: The oxygen sensor has a self diagnostic function. When it detects its own fault or abnormal monitoring data, it can send a fault prompt signal to the vehicle dashboard in a timely manner, making it convenient for car owners to detect and carry out maintenance in advance
