• Electrodes made of a gas-permeable platinum layer
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Oxygen readings help fine-tune the air-fuel mixture for fuel economy and lower exhaust emissions
• Made for its specific application and position on the vehicle, and provides the diagnostic feedback the ECU requires
