The 2017 Subaru WRX is a beloved model among car enthusiasts, known for its performance and handling. However, like many turbocharged engines, it can suffer from oil bumming, which can negatively impact performance and longevity. One effective solution to this issue is the installation of a Perrin catch can. This article explores how a Perrin catch can installation prevents oil bumming and can even add up to 9 horsepower to your WRX.
Understanding Oil Bumming
Oil bumming occurs when oil vapor from the engine is drawn into the intake system. This can lead to several issues, including:
- Carbon buildup on intake valves
- Reduced engine performance
- Increased oil consumption
For turbocharged engines like the WRX, the problem can be exacerbated due to higher pressures and temperatures. Understanding the causes and effects of oil bumming is crucial for maintaining your vehicle’s performance.
What is a Catch Can?
A catch can is an aftermarket device designed to capture oil vapors and prevent them from entering the intake system. It works by:
- Collecting oil vapor before it reaches the intake manifold
- Allowing only clean air to enter the engine
- Reducing carbon buildup and improving overall engine efficiency
The Perrin catch can is specifically designed for the Subaru WRX, ensuring a perfect fit and optimal performance. Its installation can significantly enhance the longevity and efficiency of your engine.
Benefits of Installing a Perrin Catch Can
Installing a Perrin catch can on your 2017 Subaru WRX offers several advantages:
- Prevents oil bumming and reduces carbon buildup
- Enhances engine performance by maintaining cleaner intake
- Potentially adds up to 9 horsepower
- Improves engine longevity and reliability
- Easy installation process with minimal modifications
These benefits make the Perrin catch can a worthwhile investment for any WRX owner looking to enhance their vehicle’s performance.
How Installation Works
Installing a Perrin catch can is a straightforward process. Here’s a step-by-step guide:
- Gather necessary tools: socket set, wrenches, and the Perrin catch can kit.
- Locate the PCV (Positive Crankcase Ventilation) system in your WRX.
- Disconnect the PCV hose from the intake manifold.
- Install the catch can in a suitable location, ensuring it is secure.
- Connect the hoses from the catch can to the PCV system.
- Double-check all connections and ensure there are no leaks.
Following these steps will ensure that your catch can is installed correctly and functioning as intended.
Performance Gains
One of the most appealing aspects of a Perrin catch can is the potential for increased horsepower. By preventing oil bumming and keeping the intake system clean, the engine can operate more efficiently. This efficiency can translate into:
- Improved throttle response
- Smoother acceleration
- Increased overall horsepower, with reports of gains up to 9 hp
These performance gains can make a noticeable difference in your driving experience, enhancing both everyday driving and spirited runs.
