What is 1.8T O2 Sensor Spacer?
A 1.8T O2 sensor spacer is a device that is used to move the rear oxygen sensor (O2 sensor 2) further away from the catalytic converter. This is done to trick the engine computer into thinking that the catalytic converter is more efficient than it actually is. This can be useful for vehicles that have a high-flow catalytic converter or a test pipe, as these devices can cause the engine computer to throw a check engine light for catalyst inefficiency.
O2 sensor spacers are typically made of metal or plastic and are available in a variety of lengths. The length of the spacer will depend on the specific vehicle and the desired results.
It is important to note that O2 sensor spacers are not a legal modification in all areas. In some jurisdictions, it is illegal to modify a vehicle’s emissions control system. It is important to check the laws in your area before installing an O2 sensor spacer.
Here are some of the benefits of using a 1.8T O2 sensor spacer:
- It can eliminate the check engine light caused by a high-flow catalytic converter or test pipe.
- It can improve fuel economy by allowing the engine computer to run the engine in a more efficient manner.
- It can increase power and torque by allowing the engine to breathe more freely.
Here are some of the drawbacks of using a 1.8T O2 sensor spacer:
- It is not a legal modification in all areas.
- It can reduce the catalytic converter’s efficiency, leading to increased emissions.
- It can cause the engine to run richer than it should, leading to reduced fuel economy and increased emissions.
Whether or not to use a 1.8T O2 sensor spacer is a personal decision. It is important to weigh the benefits and drawbacks carefully before making a decision.
