Upgrade and restore peak Mazda RX-8 performance with this upstream front oxygen sensor from IWOKPHD. Specifically designed for the 1.3L R2 gasoline engine, it continually monitors the air-fuel ratio to guide the ECU in delivering precise fuel injectors and optimal ignition timing. The result is steadier idle, smoother acceleration, and cleaner exhausts—especially important for RX-8 models from 2009 to 2011 (Grand Touring, R3, Sport, Touring) where sensor wear can impact drivability and emissions.
This sensor is a direct-fit, OEM-equivalent replacement (OEM part number N3R1-18-8G1), built as a 100% brand-new, tested unit. With a heated design and piezoelectric sensing element, it warms quickly and provides accurate readings across a wide range of operating conditions. Each unit is prepared for reliable installation and long-term performance, ensuring your RX-8 maintains its original responsiveness and efficiency.
