The Audi S3 is a car that commands attention and respect on the road. It’s not just its sleek design and luxurious interior that make heads turn; it’s the powerful performance under the hood that truly sets it apart. Among the various aspects that automotive enthusiasts often inquire about are the dimensions of the intercooler, with questions like “What size is the intercooler on the Audi S3 2009?” and “What size is the intercooler on the Audi S3 2007?” Additionally, the allure of improved performance leads many to consider an Audi S3 intercooler upgrade. We’ll dive into the details of the intercooler on the Audi S3, explore its connection with the turbocharger, discuss the advantages of a larger intercooler, and also address vital questions related to sizing and potential upgrades.

What Size Turbo Does an Audi S3 Have?

The turbocharger is a fundamental element in enhancing the power and efficiency of modern internal combustion engines. In the case of the Audi S3, a 2.0-liter turbocharged inline-four engine reigns supreme. This remarkable engine boasts cutting-edge technology, including direct fuel injection and a turbocharger to optimize power output.

The size of the turbocharger can significantly impact the engine’s performance. In the case of the Audi S3, the precise specifications of the turbocharger can vary slightly based on the model year and specific trim level. However, in general, the Audi S3 is equipped with a single twin-scroll turbocharger. This type of turbocharger improves throttle response and minimizes turbo lag by dividing the exhaust gases into separate streams that are directed at the turbine wheel. This design optimizes energy transfer to the turbocharger, resulting in quicker spooling and better overall performance.

What Turbo Does the Audi S3 Have?

The turbocharger found in the Audi S3 is a product of advanced engineering and precise design. It’s typically a BorgWarner K04 series turbocharger, which has become somewhat of an industry standard for performance-oriented vehicles. The BorgWarner K04 turbocharger is known for its ability to deliver impressive boost levels without sacrificing reliability or longevity.

This specific turbocharger is designed to handle higher levels of boost pressure, which in turn leads to greater horsepower and torque outputs. When combined with the Audi S3’s 2.0-liter engine, the BorgWarner K04 turbocharger delivers a satisfying blend of power and efficiency, resulting in a thrilling driving experience.

What Is the Advantage of a Bigger Intercooler?

Now, let’s shift our focus to the intercooler – a crucial component that plays a pivotal role in the turbocharged engine’s performance. The intercooler is essentially a heat exchanger that cools down the compressed air generated by the turbocharger before it enters the engine’s combustion chambers. Cooler air is denser, which means it contains more oxygen molecules. This increased oxygen intake leads to more efficient combustion and greater power output.

While the stock intercooler in the Audi S3 is well-engineered, many enthusiasts opt for aftermarket intercoolers that are larger in size. The advantage of a bigger intercooler lies in its increased cooling capacity. When the intercooler has more surface area and volume, it can dissipate heat more effectively, resulting in cooler and denser intake air.

The benefits of a larger intercooler include:

Improved Performance 

Cooler and denser air entering the engine allows for more efficient combustion, which translates to higher horsepower and torque figures.


A larger intercooler can maintain consistent performance even during spirited driving sessions, reducing the likelihood of heat soak that can hinder performance.

Safety Margin 

Upgrading to a larger intercooler provides a safety margin against potential heat-related issues, especially in high-performance applications where engine temperatures can rise significantly.

Tuning Potential 

If you’re into tuning and performance upgrades, a larger intercooler can accommodate higher levels of boost without causing the intake air temperature to spike.


Lowering the intake air temperature can also contribute to the longevity of the engine components, as cooler air reduces stress on the internal parts.

Is Audi S3 4-Wheel Drive?

Yes, the Audi S3 is indeed equipped with a renowned all-wheel-drive system. Audi’s Quattro all-wheel-drive technology has been a hallmark of the brand for decades, and the S3 benefits from this technology as well. The Quattro system provides enhanced traction and stability by distributing power to all four wheels, ensuring optimal grip in various driving conditions.

In the Audi S3, the Quattro system works harmoniously with the powerful engine and precise handling characteristics, making it an ideal choice for those seeking both performance and control. Whether you’re tackling a twisty mountain road or navigating through adverse weather conditions, the Quattro system in the Audi S3 is designed to inspire confidence and elevate the driving experience.

The Audi S3 is a high-performance machine that doesn’t cut corners when it comes to delivering power and precision. Its intercooler and turbocharger work hand in hand to optimize performance, and the option to upgrade to a larger intercooler opens the door to even more exciting possibilities. However, it’s essential to be aware of potential issues that can arise, such as an intercooler leak fix to maintain optimal performance. Keeping an eye out for damaged intercooler fins and learning how to check if the intercooler is working can save you from potential headaches down the road. If you ever hear an unusual intercooler leak sound, addressing it promptly can prevent further damage. Moreover, understanding what happens when an intercooler pipe comes off underscores the importance of regular maintenance and vigilance. Whether you’re driving an Audi S3 from 2009 or 2007, or even considering an Audi S3 8P intercooler upgrade, embracing the intricate symphony of engineering excellence beneath the hood will undoubtedly enrich your appreciation for the road ahead.
