奔驰氧传感器 0035428518 精准控制空燃比 提升排放性能。

This oxygen sensor is designed for Mercedes-Benz C-Class (W204, 2007-2014), E-Class (W212, 2009-2016), and M-Class (W166, 2011-2019) with M272 or M276 engines in 2.5L, 3.0L, and 3.5L displacements. It accurately monitors exhaust oxygen content and feeds a signal to the ECU to optimize the air-fuel ratio, improving combustion efficiency and reducing exhaust. OEM number 0035428518 can be cross-checked with original parts to ensure full compatibility with Mercedes systems. Replacement difficulty is medium; recommend using a professional O2 sensor socket to avoid thread damage; applying anti-seize before installation can extend life. For B2B buyers, this sensor uses a high-density ceramic element with superior high-temperature tolerance, reducing faults caused by signal delay, suitable for bulk purchase for repair shops or fleets.
