Oxygen Sensor Wideband Lambda 5 Wire for Mercedes-Benz C Class E Class SLK 2007-2014
Upgrade your Mercedes-Benz with the WEIDA Auto Parts 5-Wire Wideband Oxygen Sensor, crafted for precision monitoring of the air-fuel ratio in 2007–2014 C-Class, E-Class, and SLK models. This OEM-equivalent sensor delivers fast warm-up, stable lambda readings, and robust performance across engine temperatures, helping your vehicle maintain optimal combustion, boost efficiency, and reduce emissions.
Built as a heated, 5-wire sensor with magnetic induction sensing, it responds quickly to ECU demands, supporting accurate feedback for closed-loop fuel management. Replacing a worn or drifting sensor with this wideband unit helps prevent erratic idle, improves throttle response, and preserves catalytic converter health by keeping the air-fuel balance within intended targets. With OEM compatibility (OE No. A0065422718) and MB-specific measuring range, you can trust a precise fit and reliable performance aligned with factory specifications.
Designed for reliability and longevity, this sensor is manufactured to meet or exceed original equipment standards and is ready to be installed in compatible MB engines. It is a practical choice for maintenance, repair, or performance tuning projects where accurate lambda measurement is critical for fuel efficiency and emissions compliance.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
