BYD Peugeot Oxygen Sensor 258006028 / 9635978280 / 1086001114, compatible with multiple vehicles, one unit solves emission problems.

When your vehicle exhibits idle instability, weak acceleration, noticeably increased fuel consumption, and the engine fault light on the dash (usually codes P0130 or P0141), this indicates aging oxygen sensors that can no longer accurately monitor exhaust oxygen content. When functioning properly, the sensor feeds real-time air-fuel ratio signals to the ECU to ensure complete combustion, reducing emissions, boosting power, and saving fuel. This product OEM numbers are 258006028 / 9635978280 / 1086001114, suitable for multiple models such as BYD, Peugeot, etc., with strong universality. Installation notes: operate only with a cold engine, use a dedicated socket to remove to avoid thread damage; clean the exhaust interface before installation and apply a small amount of anti-galling agent; tightening torque is recommended at 45-55 N·m.
