The IWOKPHD Oxygen Sensor Upstream is the precise, ready-to-install replacement you need for BMW X3 models and a wide range of BMW variants. As an upstream oxygen sensor, it sits before the catalytic converter to monitor exhaust gas composition and send real-time feedback to the engine control unit. This enables optimal air-fuel balance, better fuel efficiency, smoother idle, and reduced emissions—helping your BMW run cleaner and more responsively. Built to match OEM specifications, this sensor supports quick warm-up and reliable performance even in challenging exhaust conditions.

Designed with a heated type and magnetic induction sensing, this upstream sensor delivers fast, accurate readings and robust durability. It carries OEM numbers such as 11788631047 and ES#3213360, ensuring compatibility across multiple BMW models and engine configurations. Brand assurance comes from IWOKPHD, with parts manufactured to meet or exceed original performance. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

This sensor is compatible with a broad array of BMW models beyond the X3, including:

  • BMW 1 Series (F20/F21): 116i, 118i, 120i, 125i (2015-), engines B38 B15 A, B48 B20 A
  • BMW 2 Series Convertible (F23): 218i, 220i, 230i (2015-)
  • BMW 2 Series Coupe (F22/F87): 218i, 220i, 230i (2015-)
