Upstream Air-Fuel Ratio Oxygen Sensor for Mercedes-Benz C250 & SLK250 (2012-2015)

Upgrade your Mercedes-Benz with a precise upstream oxygen sensor designed for the C250 and SLK250 models from 2012 to 2015. This IWOKPHD unit is a direct-fit upstream O2 sensor that monitors the air-fuel ratio (lambda) and feeds real-time data to the engine control unit to optimize combustion. With a built-in heating element for fast warm-up, it delivers quicker, more reliable readings during cold starts and across varying driving conditions. Compatible with 1.8L turbo engines in the listed models, it serves as a robust replacement for the original part A0065422718, helping maintain efficient fuel use and reduced emissions.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Benefits & Tips

  • Precise upstream O2 readings improve ECU control of the air-fuel ratio, contributing to smoother performance and better fuel efficiency on C250 and SLK250 (2012–2015).
  • The built-in heater ensures rapid sensor warm-up, delivering stable signals sooner and improving cold-start response.
  • If you notice rough idle, hesitation, or a persistent check engine light related to the oxygen sensor, consider replacing with this genuine-style upstream sensor to restore proper Lambda feedback.
