日产氧传感器 22693-1KC0A / 211500-7530，高效燃烧优化配件

Nissan oxygen sensor 22693-1KC0A directly replaces the original factory number, and is also compatible with 211500-7530 and 234-9105, with strong universality. Its core function is to monitor exhaust oxygen content and feed back to the ECU to adjust the air-fuel ratio, ensuring more efficient combustion. Suitable for 1.6L and 2.0L NissanSentra/Versa/Nissan Sunny models; after installation, it can significantly improve high fuel consumption and weak acceleration. If the engine warning light lights up, idle is unstable, or the exhaust pipe emits black smoke, it is basically due to aging oxygen sensor; replacement is recommended timely.
