雅尊06-11/霸锐氧传感器39210-3C200，可靠耐用。

This 39210-3C200 oxygen sensor directly replaces Hyundai Grandeur 2006-2011 and Kia Borui models; broadly compatible; install and use immediately. It monitors oxygen content in exhaust and sends signal to ECU to precisely control air-fuel ratio; ensures engine combustion efficiency. Compatible with Hyundai Grandeur (2006-2011) and Kia Borui; other platforms may be compatible. Replacement can fix common issues like high fuel consumption, weak acceleration, and excessive emissions; engine runs smoother. If idle is unstable, exhaust emits black smoke, or check engine light on, oxygen sensor aging is likely; replace.
