The Subaru WRX has long been celebrated for its performance and rally heritage. Enthusiasts are always looking for ways to enhance their vehicles, and one effective upgrade is the installation of a wideband oxygen sensor. In this article, we will explore the real-world results of installing the PLX Devices wideband sensor on a Subaru WRX, focusing on the performance gains and improvements in fuel economy.
Understanding Wideband Oxygen Sensors
Wideband oxygen sensors are advanced sensors that provide a more accurate measurement of the air-fuel ratio compared to traditional narrowband sensors. This accuracy allows for better tuning of the engine, leading to enhanced performance and efficiency. The PLX Devices wideband sensor is known for its precision and reliability, making it a popular choice among car enthusiasts.
Installation Process
Installing the PLX Devices wideband sensor in a Subaru WRX involves several steps. Below is a general overview of the installation process:
- Gather necessary tools and materials, including the PLX wideband sensor kit.
- Locate the optimal position for the sensor in the exhaust system.
- Remove the necessary components to access the exhaust pipe.
- Install the wideband sensor in the designated location.
- Connect the wiring harness to the vehicle’s ECU for data monitoring.
- Test the sensor to ensure proper functionality.
Performance Gains
After the installation of the PLX Devices wideband sensor, many Subaru WRX owners reported significant performance improvements. One of the most notable gains was an increase of up to 12 horsepower. This increase can be attributed to the enhanced tuning capabilities provided by the wideband sensor, allowing for a more optimal air-fuel mixture.
Improved Throttle Response
In addition to the horsepower gain, drivers also experienced improved throttle response. The precise readings from the wideband sensor allow for quicker adjustments to the fuel mixture, resulting in a more responsive driving experience. This is particularly beneficial during acceleration and when navigating tight corners.
Enhanced Fuel Economy
One of the most appealing aspects of upgrading to a wideband sensor is the potential for better fuel economy. Many Subaru WRX owners found that their fuel efficiency improved after installation. The accurate readings provided by the PLX Devices sensor allow for more efficient combustion, which can lead to savings at the pump.
Real-World Fuel Economy Results
In real-world driving conditions, some drivers reported an increase in fuel economy by as much as 2-4 miles per gallon. This improvement can make a noticeable difference, especially for those who use their WRX as a daily driver. The combination of performance gains and enhanced fuel efficiency makes the PLX Devices wideband sensor a worthwhile investment.
Conclusion
The installation of the PLX Devices wideband sensor on a Subaru WRX has proven to deliver real-world results, including a gain of 12 horsepower and improved fuel economy. For enthusiasts looking to enhance their vehicle’s performance while also benefiting from better efficiency, this upgrade is an excellent choice. By investing in quality components like the PLX wideband sensor, Subaru WRX owners can enjoy a more powerful and efficient driving experience.
