Upgrade your Toyota’s exhaust monitoring with the IWOKPHD Downstream Oxygen O2 Sensor designed for the Corolla and Matrix 1.8L. This downstream sensor measures exhaust gases after the catalytic converter, helping the engine control module optimize fuel delivery and emissions for cleaner operation and better fuel efficiency. It’s a reliable replacement that restores proper O2 readings and supports smooth engine performance.

Built to fit a range of 1.8L Toyota models from 2003–2008, including Corolla and Matrix, this sensor matches a broad set of OEM numbers to simplify replacement. Its heated design reduces warm‑up time, delivering stable readings quickly across temperature changes for consistent performance on the road. Compatibility with the 1ZZFE engine and FWD configurations makes it a practical, straightforward install for daily drivers and weekend enthusiasts alike.

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