The Subaru STI is renowned for its performance, but enthusiasts are always looking for ways to enhance their driving experience. One popular modification is the installation of an oil cooler, and many have turned to the Perrin Oil Cooler for its proven results. In this article, we will explore the real-world outcomes of installing the Perrin Oil Cooler on a Subaru STI, specifically focusing on the reported 20 horsepower increase.
Understanding the Importance of Oil Cooling
Engine oil plays a critical role in maintaining optimal engine performance. It lubricates moving parts, reduces friction, and helps in heat dissipation. However, during high-performance driving, oil temperatures can soar, leading to decreased performance and potential engine damage. This is where an oil cooler comes into play.
What is the Perrin Oil Cooler?
The Perrin Oil Cooler is designed specifically for Subaru vehicles, particularly the STI. It is engineered to lower oil temperatures, thereby improving engine efficiency and performance. The cooler features a large core that increases the surface area for heat dissipation, ensuring that the oil remains at an optimal temperature even during intense driving conditions.
Installation Process
Installing the Perrin Oil Cooler is a straightforward process, but it requires some mechanical knowledge. Below are the general steps involved in the installation:
- Gather necessary tools and materials.
- Remove the front bumper to access the engine bay.
- Disconnect the existing oil lines.
- Mount the Perrin Oil Cooler in the designated area.
- Reconnect the oil lines and ensure there are no leaks.
- Reinstall the front bumper and check all connections.
Real-World Results
After installing the Perrin Oil Cooler, many Subaru STI owners have reported significant improvements in performance. One of the most notable outcomes is the increase in horsepower. Here, we break down the results based on user feedback and dyno tests.
Reported Horsepower Gains
Users have consistently reported an increase of approximately 20 horsepower after the installation of the Perrin Oil Cooler. This boost in power can be attributed to the improved oil temperature management, which allows the engine to perform more efficiently.
Additional Performance Benefits
Aside from the horsepower increase, the Perrin Oil Cooler provides several other performance benefits:
- Improved throttle response.
- Enhanced engine longevity due to better oil temperatures.
- More consistent performance during track days or spirited driving.
