What Is an 02 Sensor Spacer? An oxygen sensor spacer is a small tube that fits between the exhaust header and your vehicle’s oxygen sensor. You will often see them referred to as O2 spacers, or simply as O2S spacers. They are designed primarily to help prevent the oxygen sensor from melting by protecting it from direct heat exposure. However, they also serve a secondary purpose in that they slow down the amount of time it takes for exhaust gases to reach the sensor.
For this reason, oxygen sensors that are designed to be used with O2S spacers can last much longer than those that are not. In addition, the wire leading away from the sensor is also better protected from excessive heat when an 02 spacer is installed. When you install an O2 spacer between the header and the O2 sensor, you will reduce overall exhaust gas temperatures coming out of your engine, which can improve fuel economy at higher speeds or when driving in stop-and-go traffic situations.
Before installing an 02 spacer, check your vehicle’s owner’s manual to verify that it is compatible with any warranty requirements or rules pertaining to emissions testing in your area before installing one on your vehicle.

An O2 sensor spacer is a small, tubular device that fits between your exhaust header and the oxygen sensor itself. The purpose of an O2 spacer is to keep the exhaust header from melting the O2 sensor itself.
An oxygen sensor is a device that measures how much oxygen there is in the exhaust stream. It’s important for this measurement because it tells you when your engine needs more fuel (which can be harmful). When you open up your throttle, more air rushes in and burns with more fuel, which creates extra energy and heat as waste products. The faster you drive or load on your engine, the higher its temperature gets—and this can easily destroy an unprotected O2 sensor!
While the primary purpose of an O2 spacer really is to keep the exhaust header from melting the O2 sensor itself, they also serve a secondary purpose by extending the length of time it takes for the exhaust gasses to reach the sensor.

The longer it takes for your car’s ECU to detect that there’s something wrong with your engine and then decide whether or not to throw on a check-engine light, the longer you’ll have before your car starts emitting smoke and suffering serious damage.
However, if you’re driving an older vehicle (or even one newer than about 1996) that isn’t equipped with any type of oxygen sensor at all—such as many vehicles manufactured prior to 1990—then this won’t apply. In fact, some manufacturers actually recommend installing spacers in these cars anyway because they can reduce carbon buildup on other components such as catalytic converters or manifolds.
In summary: If you’re looking for a way to improve performance while reducing emissions and improving fuel efficiency, then buying an O2 spacer may be just what you need!
Sensors that are designed to be used with spacers can last much longer, because they do not get as hot
Sensors that are designed to be used with spacers can last much longer, because they do not get as hot. This is because the sensor itself is located at a distance from the engine. In this way, it is able to do its job without being damaged by excessive heat.
Spacers also help protect other parts of the exhaust system from damage caused by excessive heat or severe vibrations.
The wire that transmits data from the sensor is also protected from excessive heat
In addition to protecting the sensor from vibration, corrosion, excessive heat and moisture, the spacer also keeps this sensitive wire away from dirt. This helps you avoid problems like a faulty O2 sensor reading and poor fuel economy.
When you install an O2 spacer between the header and the O2 sensor, you will reduce overall exhaust gas temperatures coming out of your engine, which can improve fuel economy
When you install an O2 spacer between the header and the O2 sensor, you will reduce overall exhaust gas temperatures coming out of your engine, which can improve fuel economy.
In addition to improving fuel economy, a good spacer will also reduce the risk of melting your oxygen sensors since it helps keep all that hot air from being trapped too close to them. This is especially important because many aftermarket headers are designed with a smooth surface so they don’t get as hot in order to prevent this problem.
When installing an O2 sensor spacer on a car with aftermarket headers that have been modified for optimal performance (and therefore aren’t as efficient), this can create an issue where heat builds up around your car’s exhaust system and melts sensors over time. That’s why using a quality spacer like ours is essential—it helps keep things cool by dispersing excess heat!
Before installing an O2 spacer, make sure you check your vehicle’s owner’s manual to verify it is compatible
Before installing an O2 spacer, you should make sure it is compatible with your vehicle. To do this, check the owner’s manual to see if it is listed as an approved part. Check the size of the spacer (the distance between the two pipes) and its length, as well as its diameter and type (such as a straight pipe). Also check what material it is made from – some are made from silicone or plastic while others may be metal or something else entirely (like carbon fiber).
A spacer can help your oxygen sensors last longer and prevent them from overheating
- A spacer can help your oxygen sensors last longer and prevent them from overheating.
- A spacer can extend the life of your oxygen sensors, which means that you won’t have to replace them as often. This will save you money on future repairs and maintenance costs.
- An 02 sensor spacer makes sure that the engine runs at its best efficiency, leading to lower fuel consumption rates.
Conclusion
Because the oxygen sensor spacer helps to reduce overall exhaust gas temperatures, it can also help improve fuel economy. The main purpose of an O2 sensor is to measure the amount of oxygen in the exhaust gases, which allows the engine’s computer to make adjustments for optimal fuel-to-air ratio. So when temperatures are reduced, there is less chance that these measurements will be skewed due to high heat levels coming out of your engine. This means your vehicle will use less gas overall and you can save money on fuel costs over time.
