多车型氧传感器 39210-2G720 06E906265R 06E906265AK 直插替换无忧

When your vehicle shows idle instability, noticeably higher fuel consumption, sluggish acceleration, or a check engine light, it usually indicates aging or failed oxygen sensors unable to monitor exhaust oxygen content accurately. This part, when functioning, provides real-time feedback of the air–fuel ratio to the ECU, helping maintain optimal combustion efficiency, reduce emissions, and save fuel. Fits OEM numbers 39210-2G720, 39210-2G710, 06E906265R, 06E906265AK for many modern, Hyundai, Kia, and VW models. Ensure sensor threads are clean and apply a small amount of anti-seize to avoid over-tightening and damage; direct plug-in design requires no extra wiring.
