• Restoring proper exhaust gas feedback to the engine control system
• Correcting drivability concerns tied to inaccurate air-fuel mixture readings
• Replacing a sensor with the correct 555 mm overall length and square connector

Installation Notes and Tips

Verify the vehicle’s front sensor location, connector shape, thread size, and overall length before installation. Compare the original sensor wiring and mounting style to the Delphi ES10951 to confirm a proper match for your Mazda Miata. Follow the included instruction sheet and inspect the exhaust bung threads before tightening the sensor.
