The Audi S4 B8 is a high-performance vehicle that combines luxury with power. However, like any performance car, it requires proper maintenance to ensure longevity and efficiency. One of the best modifications you can make to protect your engine is the installation of a catch can. This article will guide you through the process of installing a catch can on your Audi S4 B8, and how it can help you achieve up to 9 horsepower gains.
What is a Catch Can?
A catch can is a device that captures oil vapors and other contaminants from the crankcase ventilation system before they can enter the intake manifold. This helps to prevent carbon buildup on the intake valves, which can lead to engine performance issues over time.
Benefits of Installing a Catch Can
- Improved Engine Performance: By reducing carbon buildup, your engine runs more efficiently.
- Increased Horsepower: Many users report gains of up to 9 hp after installation.
- Extended Engine Life: A cleaner intake system leads to less wear and tear on engine components.
- Better Fuel Economy: Improved combustion efficiency can lead to better mileage.
Tools and Materials Needed
- Catch can kit
- Ratchet and socket set
- Wrenches
- Hose clamps
- Silicone hoses (if necessary)
- Drill and drill bits
- Safety goggles
- Gloves
Step-by-Step Installation Guide
Step 1: Preparation
Before you begin the installation, ensure that your Audi S4 B8 is parked on a flat surface and the engine is cool. Gather all the tools and materials needed for the installation.
Step 2: Locate the PCV System
The Positive Crankcase Ventilation (PCV) system is typically located near the engine cover. Remove the engine cover by unscrewing the bolts or clips holding it in place.
Step 3: Disconnect the PCV Hose
Carefully disconnect the PCV hose from the intake manifold. This hose will need to be rerouted to the catch can.
Step 4: Mount the Catch Can
Choose a suitable location for the catch can. It should be easily accessible for maintenance but away from heat sources. Use the provided mounting brackets to secure the catch can in place.
Step 5: Connect the Hoses
Connect the PCV hose from the engine to the inlet of the catch can. Then, connect a hose from the outlet of the catch can to the intake manifold. Ensure all connections are secure and use hose clamps if necessary.
Step 6: Check for Leaks
Start the engine and let it idle for a few minutes. Check all connections for any signs of leaks. If everything is secure, you are ready to go!
Maintenance Tips
- Regularly check the catch can for oil accumulation and empty it as needed.
- Inspect all hoses and connections for wear and tear.
- Keep the catch can clean to ensure optimal performance.
Conclusion
Installing a catch can on your Audi S4 B8 is a straightforward process that can significantly enhance your engine’s performance and longevity. With the potential for up to 9 horsepower gains, this modification is a worthwhile investment for any Audi enthusiast. Follow the steps outlined in this guide, and enjoy a cleaner, more efficient engine.
