The APEXi Catch Can is a popular modification among Subaru WRX enthusiasts, aimed at improving engine performance and longevity. This guide will walk you through the installation process and discuss the potential power gains associated with this modification.
What is an APEXi Catch Can?
An APEXi Catch Can is designed to capture oil vapors and contaminants from the engine’s crankcase ventilation system. By preventing these substances from entering the intake system, it helps maintain cleaner combustion, which can lead to better performance and efficiency.
Benefits of Installing an APEXi Catch Can
- Reduces oil consumption
- Improves engine performance
- Extends engine life
- Enhances throttle response
- Prevents carbon build-up in the intake system
Tools Required for Installation
- Socket set
- Wrenches
- Drill with drill bits
- Hose cutters
- Zip ties
- Safety glasses
Installation Steps
Step 1: Preparation
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Gather all the necessary tools and the APEXi Catch Can kit.
Step 2: Locate the Crankcase Ventilation System
Open the hood and locate the crankcase ventilation system. This is typically found near the engine block, where the PCV (Positive Crankcase Ventilation) valve is located.
Step 3: Remove Existing Hoses
Using your socket set, carefully remove the existing hoses connected to the PCV valve. Be sure to keep these components as you may need them for the installation of the catch can.
Step 4: Install the Catch Can
Position the APEXi Catch Can in a suitable location within the engine bay. Ensure it is secured and accessible for maintenance. Use zip ties or brackets to hold it in place.
Step 5: Connect Hoses
Attach the hoses from the PCV valve to the inlet and outlet ports on the catch can. Ensure that the connections are tight to prevent any leaks.
Step 6: Check for Leaks
Start the engine and let it idle for a few minutes. Check for any leaks around the hoses and connections. If everything looks good, you are ready to go!
How Much Power Does It Add?
The power gains from installing an APEXi Catch Can can vary based on several factors, including the condition of your engine and other modifications you may have. Generally, users report improvements in throttle response and overall engine efficiency, which can translate to a modest increase in horsepower.
Conclusion
Installing an APEXi Catch Can on your Subaru WRX can be a beneficial modification that enhances engine performance and longevity. By following the installation steps outlined in this guide, you can ensure a successful setup that helps keep your engine running smoothly.
