The Subaru WRX is a beloved vehicle among car enthusiasts, known for its impressive performance and rally heritage. However, like any high-performance car, it can benefit from upgrades that enhance its efficiency and power. One such upgrade is the installation of an oil cooler. In this article, we will explore how a Mishimoto oil cooler boosted a Subaru WRX’s power by 15 horsepower.
Understanding the Importance of Oil Temperature
Engine oil plays a crucial role in maintaining the health and performance of a vehicle. It lubricates, cleans, and cools the engine components. However, as the engine operates, the oil temperature can rise significantly. High oil temperatures can lead to reduced viscosity, which compromises the oil’s ability to lubricate effectively. This can result in increased wear and tear on the engine, reduced performance, and even catastrophic engine failure.
What is an Oil Cooler?
An oil cooler is a device designed to lower the temperature of engine oil. It works by transferring heat from the oil to the air or coolant, thus maintaining optimal operating temperatures. By keeping the oil cool, an oil cooler can help improve engine performance, increase longevity, and enhance overall driving experience.
The Mishimoto Oil Cooler
Mishimoto is a well-known brand in the automotive aftermarket, specializing in performance cooling products. Their oil cooler for the Subaru WRX is designed to fit seamlessly into the engine bay while providing superior cooling capabilities. The Mishimoto oil cooler features a lightweight aluminum construction, high-efficiency core, and includes all necessary hardware for installation.
Key Features of the Mishimoto Oil Cooler
- High-efficiency core for optimal heat dissipation.
- Durable aluminum construction for lightweight performance.
- Direct-fit design for easy installation.
- Includes all necessary mounting hardware.
Installation Process
Installing the Mishimoto oil cooler on a Subaru WRX is a straightforward process that can be completed with basic tools. Here’s a brief overview of the installation steps:
- Gather necessary tools and materials.
- Remove the factory oil filter and drain the oil.
- Install the Mishimoto oil cooler in the designated location.
- Connect the oil lines to the cooler and engine.
- Refill the engine with oil and replace the oil filter.
- Start the engine and check for leaks.
Performance Gains
After installing the Mishimoto oil cooler, many Subaru WRX owners have reported noticeable performance improvements. The cooler maintains lower oil temperatures even during aggressive driving, which helps to preserve the oil’s viscosity and lubrication properties. In testing, some users have documented power gains of up to 15 horsepower, thanks to the enhanced cooling capabilities.
Factors Contributing to Power Gains
- Improved oil viscosity at higher temperatures.
- Reduced engine knock and pre-ignition.
- Enhanced overall engine efficiency.
- Better thermal management during high-performance driving.
Conclusion
The installation of a Mishimoto oil cooler can significantly enhance the performance of a Subaru WRX by maintaining optimal oil temperatures. With power gains of up to 15 horsepower, this upgrade is a worthwhile investment for any WRX enthusiast looking to improve their vehicle’s performance and longevity. Whether you are a weekend racer or a daily driver, an oil cooler is an essential component for achieving the best from your Subaru WRX.
