名爵氧传感器 MHK100728 直接安装 无需修改

This MG oxygen sensor directly replaces original MHK100728; universal compatibility, no modifications needed. It monitors oxygen content in exhaust and helps the engine computer adjust the air-fuel ratio to ensure combustion efficiency. Compatible with MG models such as MG6 and older MG3 variants. If the vehicle shows increased fuel consumption, weak acceleration, or the engine check light is on, replacing this sensor can restore power and fuel economy. Common aging symptoms include unstable idle, black smoke from the exhaust, or failing emissions tests.
