The BMW 3 Series is known for its performance and driving experience. However, many enthusiasts look for ways to enhance the power and efficiency of their vehicles. One effective method is the installation of a catch can. This article will guide you through the process of installing a catch can on your BMW 3 Series, which can boost power by up to 12 horsepower for under $150.
What is a Catch Can?
A catch can is a device that helps to prevent oil vapors from entering the intake system of your engine. By capturing these vapors, a catch can reduces carbon buildup, improves engine efficiency, and can even lead to increased horsepower. Installing a catch can is a relatively simple modification that can provide significant benefits.
Benefits of Installing a Catch Can
- Reduces carbon buildup in the intake system.
- Improves engine efficiency and performance.
- Increases horsepower by up to 12 HP.
- Extends engine life by preventing oil contamination.
- Cost-effective modification under $150.
Tools and Materials Needed
- Catch can kit (specific for BMW 3 Series)
- Ratchet and socket set
- Wrenches
- Hose clamps
- Silicone hoses (if not included in the kit)
- Drill (if mounting is required)
- Safety glasses
Installation Steps
Step 1: Prepare Your Workspace
Before starting the installation, ensure you have a clean and organized workspace. Gather all the tools and materials needed for the installation. Make sure the engine is cool and the battery is disconnected to ensure safety during the process.
Step 2: Locate the PCV System
The Positive Crankcase Ventilation (PCV) system is typically located near the engine cover. Consult your BMW 3 Series manual to identify the exact location. You will be connecting the catch can to this system.
Step 3: Remove Existing Hoses
Carefully disconnect the existing hoses connected to the PCV system. Use your ratchet and socket set to remove any clamps or fasteners. Be cautious not to damage any components during this process.
Step 4: Install the Catch Can
Mount the catch can in a suitable location in the engine bay. Ensure it is secure and will not interfere with any moving parts. If necessary, drill holes for mounting. Connect the hoses from the catch can to the PCV system, ensuring a tight fit with hose clamps.
Step 5: Reconnect the Battery
Once everything is securely connected, reconnect the battery. Start the engine and check for any leaks or issues. Monitor the catch can to ensure it is functioning correctly.
Maintenance Tips
- Check the catch can regularly for oil accumulation.
- Empty the catch can as needed, typically every few months.
- Inspect hoses and connections for wear and tear.
- Keep the area around the catch can clean to avoid contamination.
Conclusion
Installing a catch can on your BMW 3 Series is a cost-effective way to boost performance and enhance engine longevity. With the potential to gain up to 12 horsepower for under $150, this modification is a worthwhile investment for any BMW enthusiast. Follow the steps outlined in this guide, and enjoy the benefits of improved engine efficiency and power.
