AP Exhaust 530230 OE-Style Replacement Oxygen Sensor

The AP Exhaust 530230 is an OE-style replacement oxygen sensor (O2 sensor) engineered to restore proper air/fuel ratio monitoring and exhaust emissions control to compatible vehicles. Designed as a direct-fit replacement, this sensor is built to meet or exceed original equipment performance standards for a reliable, hassle-free installation.

The oxygen sensor plays a critical role in your vehicle's engine management system. Mounted in the exhaust system, it continuously monitors the level of unburned oxygen in the exhaust gases and relays that data to the Engine Control Unit (ECU). The ECU uses this information to fine-tune the air/fuel mixture in real time, optimizing combustion efficiency, fuel economy, and emissions output.

Key Features:

• OE-style design for direct-fit replacement
• Restores proper closed-loop fuel control and air/fuel ratio monitoring
• Helps reduce harmful exhaust emissions
• Engineered to meet or exceed original equipment specifications
• Supports proper catalytic converter function and longevity
• Helps resolve oxygen sensor-related check engine light codes
