捷豹XJ 2005年后氧传感器C2C25956，尾气监测关键部件

This rear oxygen sensor is designed specifically for Jaguar XJ 2005-2009 (including 3.0L V6 and 4.2L V8 engines), directly replacing the original part to monitor oxygen content in exhaust and feed back to the ECU, ensuring precise air-fuel ratio adjustment, reducing emissions and improving fuel economy. OEM number C2C25956, also compatible with Jaguar XK 2006-2009, for easy cross-check of inventory. Replacement difficulty is medium; operate with a cold engine and use a dedicated oxygen sensor socket to avoid thread damage. As a private-brand product, this sensor has undergone rigorous testing, offering stable supply and competitive pricing, suitable for bulk purchase to reduce maintenance costs.
