The Audi B8 S4 is a performance vehicle that has garnered a dedicated following among car enthusiasts. With its supercharged V6 engine, it delivers impressive power and handling. However, many owners seek to enhance their driving experience further. One of the most effective ways to achieve significant power gains is through the installation of an AWE exhaust system combined with an upgraded intake.
Understanding the B8 S4 Engine
The B8 S4 is equipped with a 3.0-liter supercharged V6 engine, producing a respectable factory output of around 333 horsepower. While this is sufficient for most drivers, the potential for increased performance is substantial. The engine’s design allows for modifications that can significantly enhance its output and responsiveness.
The Role of Exhaust Systems
Upgrading the exhaust system is one of the most popular modifications among car enthusiasts. An aftermarket exhaust, such as the AWE exhaust, not only improves the sound of the vehicle but also enhances performance. By reducing back pressure and improving exhaust flow, an upgraded exhaust can lead to noticeable power gains.
Benefits of the AWE Exhaust
- Improved exhaust flow for better engine performance.
- Enhanced sound quality, providing a more aggressive tone.
- Weight reduction compared to the stock exhaust system.
- Increased horsepower and torque output.
Intake Upgrades: A Key Component
Alongside the exhaust system, upgrading the intake is crucial for maximizing performance. The stock intake system can be restrictive, limiting airflow to the engine. An upgraded intake allows for a higher volume of air, which is essential for combustion and overall engine efficiency.
Advantages of an Upgraded Intake
- Increased airflow, leading to improved throttle response.
- Enhanced engine sound, adding to the driving experience.
- Potential for greater horsepower gains when paired with an exhaust system.
- Improved fuel efficiency under certain driving conditions.
Combining AWE Exhaust and Upgraded Intake
When the AWE exhaust is paired with an upgraded intake, the results can be astounding. The synergy between these two modifications allows for optimal airflow into and out of the engine, resulting in significant power gains. Many B8 S4 owners report increases of up to 70 horsepower with this combination.
Expected Power Gains
- Stock horsepower: 333 hp
- With AWE exhaust: +20 hp
- With upgraded intake: +30 hp
- Total potential gain: +70 hp
Installation Considerations
Installing an AWE exhaust and upgraded intake can be a straightforward process for those with mechanical experience. However, it is recommended to seek professional installation if you are not comfortable with automotive modifications. Proper installation ensures that the components function correctly and safely.
Tools Needed for Installation
- Socket set
- Wrenches
- Jack and jack stands
- Torque wrench
- Basic hand tools
Conclusion
The Audi B8 S4 is a remarkable vehicle that can be transformed into a powerhouse with the right modifications. By investing in an AWE exhaust and an upgraded intake, owners can unlock the full potential of their engines, achieving impressive power gains of up to 70 horsepower. Whether for daily driving or track use, these upgrades offer a thrilling enhancement to the driving experience.
