This downstream oxygen lambda sensor from IWOKPHD is designed for a precise, plug-and-play fit on compatible Mazda and Toyota models, helping your engine run cleaner and more efficiently. By monitoring the exhaust’s oxygen levels after the catalytic converter, it gives the engine control unit real-time data to optimize air-fuel ratio, improve cold-start behavior, and reduce emissions. With its heated design and fast-response magnetic induction sensing, this sensor responds quickly to changes in exhaust chemistry, supporting smoother idling, better throttle response, and consistent performance over time.

Benefits & Tips

  • Improve fuel efficiency and lower emissions by maintaining an optimal air-fuel mixture across driving conditions.
  • Enhance cold starts and steady idle by providing reliable oxygen readings to the ECU when the engine is warming up.
  • Direct-fit replacement for listed applications—verify compatibility with your vehicle using the part numbers provided to ensure a correct match.
