丰田普拉多/雷克萨斯GX470 LX470氧传感器89465-43010，即插即用优化尾气检测

This oxygen sensor replaces factory number 89465-43010 and is universal for Toyota Prado and Lexus GX470/LX470; plug-and-play with no wiring modification. Its core function is to monitor exhaust oxygen content and feed back to the ECU to adjust the air-fuel ratio for combustion efficiency. Installed, it can resolve excessive exhaust, warning lights, and ease annual inspections. If aging, you will notice higher fuel consumption, sluggish acceleration, or rough idle—time to replace.
