The Audi S4 is known for its impressive performance and engineering. One way to enhance its capabilities is through aftermarket intakes. In this article, we will explore the performance testing of the Audi S4 using two popular intake brands: Injen and AEM.
Understanding Performance Intakes
Performance intakes are designed to improve airflow to the engine, which can lead to increased horsepower and torque. The Audi S4, with its supercharged V6 engine, can greatly benefit from an upgraded intake system.
Intake Brands Overview
Before diving into the performance tests, it’s important to understand the two brands we will be comparing: Injen and AEM.
- Injen: Known for its innovative designs and high-quality materials, Injen offers a range of intakes that promise improved performance and sound.
- AEM: AEM is a well-respected name in the automotive aftermarket, offering intakes that focus on maximizing airflow and filtration efficiency.
Testing Methodology
To accurately compare the performance of the Injen and AEM intakes, we conducted a series of tests under controlled conditions. The following factors were considered:
- Dyno Testing: Measuring horsepower and torque on a dynamometer.
- Real-World Driving: Evaluating performance under various driving conditions.
- Sound Levels: Assessing the auditory experience of each intake.
Dyno Test Results
The dyno tests were conducted to quantify the horsepower and torque gains from each intake. Here are the results:
- Injen Intake: Produced a peak horsepower gain of 15 hp and a torque increase of 12 lb-ft.
- AEM Intake: Achieved a peak horsepower gain of 10 hp and a torque increase of 8 lb-ft.
Real-World Driving Impressions
While dyno results provide valuable data, real-world performance is equally important. During our driving tests, we noted the following:
- Injen: The throttle response was noticeably sharper, and the engine felt more responsive during acceleration.
- AEM: The intake provided a smooth power delivery, but the difference in throttle response was less pronounced compared to Injen.
Sound Comparison
The sound produced by an intake can significantly enhance the driving experience. We evaluated both intakes for their acoustic characteristics:
- Injen: Offered a deep, aggressive sound that complemented the S4’s performance.
- AEM: Provided a more subdued tone, focusing on a refined driving experience.
Conclusion
After extensive testing, it’s clear that both Injen and AEM offer quality intake systems for the Audi S4. The choice between them ultimately depends on individual preferences regarding performance, sound, and driving experience.
Final Recommendations
For those seeking maximum performance and aggressive sound, the Injen intake is the recommended choice. However, if a refined driving experience with smooth power delivery is preferred, the AEM intake is a solid option.
Further Considerations
When selecting an intake, consider the following factors:
- Compatibility with other modifications.
- Long-term reliability and maintenance.
- Personal driving style and preferences.
Final Thoughts
Upgrading the intake system of your Audi S4 can lead to significant performance improvements. Both Injen and AEM provide excellent options, making it essential to choose the one that aligns with your goals and driving habits.
