雷克萨斯氧传感器 89465-50120 原厂规格替换

This oxygen sensor directly replaces Lexus original 89465-50120; compatibility is fine with no need to modify wiring or brackets. Core function is monitoring exhaust oxygen content and feedback to ECU to adjust air-fuel ratio for engine efficiency. Fits Lexus ES, RX, NX and other 2.0L and 2.5L models. After installation, can solve high fuel consumption, weak acceleration, and engine warning light. If idle is jittery, exhaust emits black smoke, or fuel consumption suddenly rises, it’s likely aging oxygen sensor that should be replaced.
