Installation Tips
When installing new shock absorbers, it’s essential to follow manufacturer guidelines. Ensure that you have the right tools and consider professional installation if you’re not confident in your skills.
ECU Flashing
ECU flashing is one of the most effective ways to increase your B5 S4’s performance. By reprogramming the engine control unit, you can unlock additional horsepower and torque.
- Benefits: Increased power output, improved throttle response, and optimized fuel efficiency.
- Popular Tuning Options: APR, Unitronic, and GIAC.
Considerations for ECU Flashing
Before flashing your ECU, ensure that your vehicle is in good mechanical condition. It’s also advisable to use high-quality fuel to maximize the benefits of the flash.
Intake Systems
Upgrading the intake system can significantly improve airflow to the engine, resulting in better performance and sound. A high-flow intake system can help your B5 S4 breathe easier.
- Benefits: Enhanced horsepower, improved throttle response, and a sportier engine sound.

Installation and Maintenance
When installing an intake system, ensure that all connections are secure to prevent leaks. Regular maintenance, such as cleaning filters, will help maintain performance.
Exhaust Systems
Upgrading the exhaust system can lead to significant performance improvements by reducing back pressure and enhancing exhaust flow. A performance exhaust also adds a more aggressive sound to your B5 S4.
- Benefits: Increased horsepower, improved sound, and reduced weight.
- Recommended Brands: Milltek, APR, and Borla.
Choosing the Right Exhaust
When selecting an exhaust system, consider your desired sound level and performance goals. A cat-back system is a popular choice for a balance of sound and performance.
Suspension Upgrades
Improving the suspension can greatly enhance the handling characteristics of your B5 S4. Coilovers or performance springs can lower the vehicle’s center of gravity and improve cornering capabilities.
- Benefits: Better handling, improved ride quality, and adjustable ride height.
- Popular Brands: KW, H&R, and Bilstein.
Installation Considerations
When upgrading your suspension, ensure that you have a proper alignment performed afterward to maintain tire wear and handling performance.
Braking System Upgrades
Enhancing the braking system is crucial, especially as you increase your B5 S4’s power. Upgrading to larger rotors and high-performance brake pads can improve stopping power and reduce brake fade.
- Benefits: Improved stopping distance, enhanced pedal feel, and reduced fade under heavy use.
- Recommended Brands: Brembo, EBC, and StopTech.
Brake Maintenance
Regularly inspect your brake components and replace pads and rotors as needed to ensure optimal performance and safety.
Conclusion
Modifying your B5 S4 can lead to a thrilling driving experience. By carefully selecting performance upgrades, you can enhance handling, power, and overall enjoyment. Whether you choose to upgrade shock absorbers, flash the ECU, or improve the exhaust system, each modification can contribute to a well-rounded performance vehicle.
