The BMW E39 M5 is a legendary performance sedan that combines luxury with raw power. For enthusiasts looking to unlock even more horsepower, upgrading the intake and throttle body can yield significant performance gains. In this article, we will explore the best intake and throttle body upgrades that can help you achieve 30+ horsepower gains for your E39 M5.
Understanding the Importance of Intake and Throttle Body Upgrades
The intake system is crucial for the engine’s performance as it controls the airflow entering the combustion chamber. A high-performance intake can enhance airflow efficiency, allowing the engine to breathe better and produce more power. Similarly, the throttle body controls the amount of air entering the engine; upgrading to a larger throttle body can improve throttle response and increase horsepower.
Top Intake Upgrades for E39 M5
Here are some of the best intake upgrades for the E39 M5 that can help you achieve those desired horsepower gains:
- Carbon Fiber Intake System: A lightweight carbon fiber intake system can improve airflow while reducing weight. The increased efficiency can lead to noticeable power gains.
- High-Performance Air Filter: Upgrading to a high-flow air filter can significantly enhance airflow compared to the stock filter, resulting in improved engine performance.
- Cold Air Intake: A cold air intake system draws cooler air from outside the engine bay, which is denser and more oxygen-rich, leading to better combustion and more power.
- Intake Manifold Upgrade: Replacing the stock intake manifold with a performance-oriented version can optimize airflow and improve engine efficiency.
Best Throttle Body Upgrades for E39 M5
In addition to intake upgrades, consider these throttle body upgrades to maximize performance:
- Upgraded Throttle Body: Installing a larger throttle body can increase airflow to the engine, improving throttle response and power delivery.
- Throttle Body Spacer: A throttle body spacer can create a better air velocity and improve the overall performance of the engine.
- Electronic Throttle Control Upgrade: For models equipped with electronic throttle control, an upgrade can fine-tune the throttle response for better performance.
Combining Intake and Throttle Body Upgrades
For optimal results, it’s recommended to combine both intake and throttle body upgrades. This synergy can lead to enhanced airflow, improved engine efficiency, and significant horsepower gains. Here are some tips for combining these upgrades:
- Choose Compatible Components: Ensure that the intake and throttle body upgrades are compatible with each other and designed for the E39 M5.
- Consider Tuning: After upgrading your intake and throttle body, consider an ECU tune to fully realize the performance potential of your modifications.
- Monitor Engine Performance: After installation, keep track of engine performance metrics to ensure that your upgrades are functioning optimally.
Installation Tips
Installing intake and throttle body upgrades can be a straightforward process, but here are some tips to ensure a successful installation:
- Gather Necessary Tools: Before starting, make sure you have all necessary tools, including wrenches, screwdrivers, and any specialty tools required for your specific upgrades.
- Follow Manufacturer Instructions: Always follow the installation instructions provided by the manufacturer to avoid any issues.
- Take Your Time: Rushing can lead to mistakes. Take your time to ensure everything is installed correctly and securely.
Conclusion
Upgrading the intake and throttle body on your E39 M5 can lead to impressive performance gains, potentially exceeding 30 horsepower. By carefully selecting the right components and ensuring proper installation, you can transform your M5 into an even more exhilarating driving machine. Whether you’re a seasoned enthusiast or a newcomer to performance upgrades, these modifications will enhance your driving experience and showcase the true potential of the E39 M5.
