AP Exhaust 530366 Replacement Oxygen Sensor

The AP Exhaust 530366 is an aftermarket replacement oxygen (O2) sensor engineered to restore proper exhaust emissions monitoring and fuel management in compatible vehicles. Designed as a direct-fit replacement, this sensor integrates seamlessly with the vehicle's engine control module (ECM) to deliver accurate air-fuel ratio feedback and help maintain optimal engine performance.

Oxygen sensors monitor the level of unburned oxygen in the exhaust stream, signaling the ECM to adjust the fuel mixture in real time. A worn or failed O2 sensor can trigger a check engine light, reduce fuel economy, and increase exhaust emissions — making timely replacement essential.

Key Features:

• Direct-fit aftermarket replacement O2 sensor
• Engineered to meet or exceed original equipment performance standards
• Helps restore proper closed-loop fuel control and accurate air-fuel ratio monitoring
• Designed to clear O2 sensor-related diagnostic trouble codes (DTCs)
• Built by AP Exhaust (AP Emissions Technologies), a trusted name in aftermarket exhaust and emissions components
