The Audi S4 B8 is a high-performance sedan that has been a favorite among car enthusiasts since its release. Equipped with a 3.0-liter V6 engine, it boasts impressive performance figures straight out of the factory. However, for those looking to take their driving experience to the next level, APR has developed a Stage 3 upgrade package that promises to unlock the full potential of the S4 B8. In this article, we will take a closer look at the APR Stage 3 upgrade and see what it can do for the Audi S4 B8.

What is APR Stage 3 Upgrade?

APR is a well-known name in the world of high-performance tuning, and their Stage 3 upgrade is one of the most comprehensive packages available for the Audi S4 B8. The upgrade includes a host of modifications that work together to increase power and torque output, improve throttle response, and enhance overall driving dynamics. The APR Stage 3 upgrade includes the following components:

1. ECU Upgrade

The heart of the APR Stage 3 upgrade is the ECU upgrade. This involves reprogramming the engine control unit (ECU) to optimize performance. The new software adjusts the fuel, ignition, and boost parameters to increase power output and torque. The result is a significant increase in horsepower and torque figures.

2. Upgraded Turbochargers

To complement the increased boost pressure from the ECU upgrade, APR also includes upgraded turbochargers in the Stage 3 package. The new turbos feature larger compressor wheels and upgraded bearings to handle the increased boost pressure. The result is improved airflow, reduced turbo lag, and increased power output.

3. Upgraded Intercooler

To keep the intake air as cool as possible, APR includes an upgraded intercooler in the Stage 3 package. The new intercooler features a larger core and improved end tanks, which allows for better heat dissipation and increased airflow. This results in improved throttle response and increased power output.

Performance Figures

So, just how much of a difference does the APR Stage 3 upgrade make? According to APR, the Stage 3 package can increase power output to 580 horsepower and 570 lb-ft of torque. That's a significant increase over the stock figures of 333 horsepower and 325 lb-ft of torque. The increase in power and torque figures translates to improved acceleration and higher top speed. In real-world testing, the APR Stage 3 upgrade has been shown to reduce the 0-60 mph time to just 3.5 seconds, which is a full second faster than the stock time. The quarter-mile time is also significantly improved, with the Stage 3-equipped S4 B8 completing the run in just 11.8 seconds.

Driving Experience

Of course, it's not just about the numbers. The APR Stage 3 upgrade promises to enhance the overall driving experience of the Audi S4 B8. And, from all accounts, it delivers on that promise. The increased power and torque figures provide a noticeable improvement in acceleration and overall responsiveness. The reduced turbo lag also means that power delivery is smoother and more immediate. The improved throttle response and power delivery are not the only benefits of the APR Stage 3 upgrade. The upgraded intercooler also helps to keep the intake air temperature as low as possible, which means that the engine can run more efficiently and reliably. The improved airflow also means that the engine can breathe better, which contributes to a more refined and enjoyable driving experience.

Conclusion

The APR Stage 3 upgrade for the Audi S4 B8 is an impressive package that can significantly increase the performance of an already capable sedan. With horsepower figures of up to 580 and torque figures reaching 570 lb-ft, the Stage 3 upgrade offers a significant boost in power and acceleration. Of course, the APR Stage 3 upgrade is not just about the numbers. The improved driving experience and overall refinement are just as important. And, from all accounts, the Stage 3 upgrade delivers on that front as well. If you're looking to take your Audi S4 B8 to the next level, the APR Stage 3 upgrade is definitely worth considering.
