Oxygen Sensor by RICHPORTER TECHNOLOGY - OS5056

Spectra Premium oxygen sensor is engineered to detect the oxygen concentration in the exhaust gas and is primarily located in the exhaust stream. This sensor doesn't measure the air-fuel ratio directly, but it measures the variance of the oxygen content in the exhaust gas and the ambient air which it communicates back to the ECU. Spectra Premium oxygen sensors are provided with an anti-seize coating on the threads and a protective cap.

• Spectra Premium oxygen sensor is measured from Japanese ceramic sensing elements
• Provided with waterproof connectors to match the vehicle’s mating harness perfectly
• Anti-seize thread coating pre-applied on all parts
• Offered with a protective cap on all models to protect the sensing element from dirt and contamination
