• May offer similar performance to OEM sensors.

However, aftermarket sensors may not fit perfectly due to variations in specifications or quality issues.

Installing the New Oxygen Sensor

Installing a new oxygen sensor involves following these steps:

1. Properly dispose of your old sensor according to environmental regulations.
2. Locate and remove the exhaust pipe and catalytic converter.
3. Remove the exhaust manifold and oxygen sensor.
4. Install the new oxygen sensor and secure it with the exhaust pipe and catalytic converter.
