When it comes to enhancing the performance of your Audi S3, one of the most popular modifications is upgrading the intercooler. Aftermarket intercoolers promise better cooling efficiency and increased power output. But are they really worth the investment? In this article, we will explore the benefits of aftermarket intercoolers and specifically test a Mishimoto upgrade on the Audi S3.
Understanding Intercoolers
An intercooler is a crucial component in turbocharged and supercharged engines. Its primary function is to cool the air that has been compressed by the turbocharger before it enters the engine. Cooler air is denser, which means it contains more oxygen, leading to improved combustion and increased power. In this section, we will delve deeper into how intercoolers work and their importance in performance vehicles.
How Intercoolers Work
Intercoolers operate by transferring heat from the compressed air to the surrounding environment. This process typically involves:
- Air enters the intercooler through the inlet.
- The air passes through a series of fins that dissipate heat.
- Cooler air exits the intercooler and enters the engine.
By reducing the temperature of the intake air, intercoolers help prevent engine knock and improve overall efficiency.
Benefits of Aftermarket Intercoolers
Upgrading to an aftermarket intercooler can provide several advantages over the stock unit. Here are some key benefits:
- Improved Cooling Efficiency: Aftermarket intercoolers typically have larger cores and more efficient designs, allowing for better heat dissipation.
- Increased Power Output: Cooler intake air leads to more power, as the engine can burn more fuel efficiently.
- Enhanced Reliability: Upgraded intercoolers can handle higher boost levels, reducing the risk of heat-related failures.
- Better Fitment: Many aftermarket options are designed specifically for performance applications, ensuring a proper fit and function.
These benefits make aftermarket intercoolers an attractive option for those looking to boost their vehicle’s performance.
Testing the Mishimoto Intercooler on the Audi S3
To evaluate the effectiveness of an aftermarket intercooler, we decided to install a Mishimoto intercooler on our Audi S3. This section will cover the installation process, testing methods, and results.
Installation Process
The installation of the Mishimoto intercooler is relatively straightforward, but it does require some mechanical knowledge. Here’s a brief overview of the steps involved:
- Remove the front bumper to access the factory intercooler.
- Disconnect the piping and remove the stock intercooler.
- Install the Mishimoto intercooler, ensuring proper alignment with the mounting points.
- Reattach the piping and front bumper.
With the intercooler installed, it was time to conduct performance tests.
Testing Methodology
We conducted a series of tests to measure the performance improvements provided by the Mishimoto intercooler. The tests included:
- Dyno Testing: Measuring horsepower and torque before and after the installation.
- Temperature Monitoring: Recording intake air temperatures during various driving conditions.
- Real-World Driving: Assessing the overall driving experience and performance improvements.
These tests aimed to provide a comprehensive understanding of the intercooler’s impact on performance.
Results
The results of our testing were impressive. Here’s what we found:
- Horsepower Increase: The dyno tests showed an increase of approximately 15-20 horsepower at peak levels.
- Lower Intake Temperatures: We recorded a significant drop in intake air temperatures, especially during high-load conditions.
- Enhanced Throttle Response: Drivers reported a noticeable improvement in throttle response and overall drivability.
These results indicate that the Mishimoto intercooler provides substantial performance benefits for the Audi S3.
Conclusion: Are Aftermarket Intercoolers Worth It?
After testing the Mishimoto intercooler on the Audi S3, it is clear that aftermarket intercoolers can offer significant performance enhancements. With improved cooling efficiency, increased power output, and better reliability, investing in an aftermarket intercooler is a worthwhile consideration for any Audi S3 owner looking to enhance their vehicle’s performance.
Ultimately, the decision to upgrade should take into account personal performance goals and budget. However, for those serious about maximizing their vehicle’s potential, a quality aftermarket intercooler like the Mishimoto is a solid investment.
