The FAE (75021) oxygen sensor developed for Mercedes-Benz E-Class W211 (M271 Engine) maintains exhaust emission values at an ideal level, providing fuel savings and extending engine life.

  • Fast Data Transmission: Detects changes in engine operating conditions within milliseconds and transmits to the ECU.
  • Maximum Fuel Efficiency: Minimizes fuel consumption by preventing unnecessary rich mixtures.
  • Heat-Resistant Alloy: High-durability stainless body resistant to extreme temperatures and corrosion in the exhaust line.
  • Original Socket Compatibility: 100% plug-and-play compatibility with Mercedes wiring structure and cable length.

Expert Recommendation

Why FAE? Signal stability is critical in Mercedes systems; the FAE 75021 meets the resistance values of the original sensor, turning off the error light.
Installation Tip: Clean the exhaust threads before installing the new sensor. Do not touch the sensitive ceramic part at the tip of the sensor or contaminate it with oil/grease. It is recommended to reset the engine adaptation values with a diagnostic tool after replacement.
