The 2018+ Subaru WRX is known for its performance and tuning potential. However, as with any high-performance vehicle, maintaining optimal engine health is crucial. One effective way to enhance your WRX’s performance is by upgrading the EVAP (Evaporative Emission Control) system with a Mishimoto catch can. This article explores the benefits of installing a catch can and how it can improve your vehicle’s efficiency and longevity.
Understanding the EVAP System
The EVAP system in your Subaru WRX is designed to prevent fuel vapors from escaping into the atmosphere. It captures and recycles these vapors back into the engine for combustion. While this system is essential for emissions control, it can also lead to issues if not properly managed.
What is a Mishimoto Catch Can?
A Mishimoto catch can is an aftermarket component that helps manage oil vapors and contaminants that can accumulate in the intake system. By capturing these unwanted substances, a catch can prevents them from entering the engine, leading to improved performance and efficiency.
Benefits of Installing a Mishimoto Catch Can
- Improved Engine Performance: By reducing oil vapor intake, the catch can helps maintain cleaner combustion, resulting in better engine performance.
- Enhanced Fuel Efficiency: A cleaner intake system allows for more efficient fuel combustion, potentially improving your WRX’s fuel economy.
- Reduced Carbon Buildup: The catch can minimizes the risk of carbon deposits forming on intake valves, which can lead to costly repairs and maintenance.
- Increased Engine Longevity: By preventing harmful contaminants from entering the engine, a catch can contributes to a longer engine life.
- Easy Installation: Mishimoto catch cans are designed for straightforward installation, making it accessible for both DIY enthusiasts and professionals.
How a Catch Can Works
The catch can operates by intercepting the crankcase vapors before they can enter the intake manifold. As these vapors pass through the catch can, they cool down, allowing oil and other contaminants to condense and collect in the can. Only clean air is then routed back into the intake system, ensuring that your engine receives the best possible airflow.
Installation Process
Installing a Mishimoto catch can on your 2018+ Subaru WRX is a manageable task for those with basic mechanical skills. Here’s a brief overview of the installation process:
- Gather Necessary Tools: Ensure you have the tools required for the installation, such as wrenches, pliers, and a socket set.
- Locate the EVAP System: Identify the EVAP system components in your WRX.
- Mount the Catch Can: Securely mount the catch can in a suitable location in the engine bay.
- Connect Hoses: Attach the hoses from the catch can to the appropriate points in the EVAP system.
- Check for Leaks: After installation, start the engine and check for any leaks to ensure a proper seal.
Maintenance Tips
To ensure your Mishimoto catch can functions optimally, regular maintenance is essential. Here are some tips:
- Regularly Empty the Can: Check the catch can periodically and empty it as needed to prevent overflow.
- Inspect Hoses: Regularly inspect the hoses for cracks or wear and replace them if necessary.
- Clean the Can: Clean the catch can periodically to remove any buildup and ensure proper airflow.
Conclusion
Upgrading your 2018+ Subaru WRX with a Mishimoto catch can is a smart investment for any performance enthusiast. The benefits of improved engine performance, enhanced fuel efficiency, and reduced carbon buildup make it a worthwhile addition to your vehicle. With easy installation and minimal maintenance, a catch can will help you achieve the best possible performance from your WRX while contributing to its longevity.
