• Monitors exhaust gases to help cut pollutants
• Electrodes coated with a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Measures oxygen levels to help fine-tune the air-fuel mixture and fuel economy
• Gives the ECU the diagnostic feedback it needs for this application

Quick facts

Before replacing it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool. If the sensor is the cause, this one replaces it.

Fits

This is a direct-fit oxygen sensor for the 2004-2011 Mazda RX-8 1.3L and for the 1996-1998 Mazda MPV V6 3.0L. Both cars take one in the downstream position, and this listing is one sensor.
