Lexus Oxygen Sensor 89465-50120 OEM Specification Replacement

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.
