YH-Suitable for Buick front oxygen sensor 234-4119 12573721 12586996

[Oxygen sensor damage will cause]:
1. Turn on the engine failure light
2. Exhaust gas exceeds the standard and emits black smoke
3. Idle speed is unstable, and the body is shaking
4. Increased fuel consumption and blocked oil circuit
[Oxygen sensor process improvement]:
The oxygen sensor adopts a stainless steel waterproof shell and a chip package imported from Germany. The high temperature resistance can reach 800~ 1000 ° C, the exhaust gas in the cold starting phase can be reduced by more than half, and the sensing module and anti-poisoning protective layer with comprehensive heating can still maintain excellent performance after long-term use. The oxygen sensor uses a new technology, which has more platinum electrodes (omentum) made of platinum materials to achieve higher resolution and sensitivity. Imported core components are used to improve the accuracy and durability of the sensor, which is environmentally friendly and fuel-efficient.
[Eliminate faults, reduce fuel consumption, improve fuel efficiency, and save fuel]
The oxygen sensor controls the air-fuel ratio within a certain range, making the fuel more efficient and achieving the effect of fuel economy.
[Longer lifespan]
The service life of oxygen sensors is longer than that of ordinary oxygen sensors, and they are maintenance-free, reducing maintenance costs.
[Optimize engine]
Solve engine jitter and idling instability
