Active Autowerke S55 Aftercooler Kit - Performance Upgrade for Your BMW

If you own a BMW F80 M3, F82 M4, or F87 M2 Competition, you already know that the S55 motor is an engineering marvel. However, one of its weaknesses lies in the factory cooling system. The stock charge pipe, aftercooler, and heat exchanger often struggle to keep up, especially when you push your performance upgrades. Enter the Active Autowerke S55 Aftercooler Kit, a solution designed specifically for the S55 engine that not only enhances cooling efficiency but also elevates the overall performance of your ride.

Why Upgrade Your Cooling System?

As many owners have experienced, the factory aftercooler is built to handle a specific power target. Once you start pushing your S55 beyond its limits, the stock cooler can quickly lead to heat soak, resulting in higher intake air temperatures. This triggers the ECU to throttle back performance to protect the engine. The Active Autowerke aftercooler kit is engineered to prevent this issue, ensuring your car maintains optimal performance even under intense driving conditions.

Key Features of the Active Autowerke Aftercooler Kit

• High-Grade Aluminum Construction: Crafted from premium aluminum, this aftercooler outperforms the factory unit in both daily driving and competitive racing scenarios.
• Tube-and-Fin Core Design: Specifically designed for the S55, this setup includes turbulators to maximize cooling efficiency in a compact form.
• Billet Machined End Tanks: Unlike cast or folded alternatives, these end tanks ensure even water distribution, enhancing the cooling process.
• Precision Engineering: With high-quality CNC machining and TIG welding, this kit minimizes pressure loss while being lightweight for easy installation.
• Aesthetic Appeal: The visible top of the aftercooler is finished in a sleek carbon fiber coating, giving your engine bay a high-end look to match its performance capabilities.

Silicone Charge Pipes for Enhanced Flow

Along with the aftercooler, the Active silicone charge pipes replace the factory plastic pipes notorious for developing hairline fractures. These cracks can lead to boost leaks, robbing your S55 of its full power potential. The silicone design not only resists heat soak but also allows for better airflow, ensuring that all that boost pressure is effectively utilized.

Heat Exchanger: The Unsung Hero

The included heat exchanger is often overlooked but plays a crucial role in maintaining performance. While it may not yield significant power gains, it prevents heat soak, allowing your intercooler system to operate efficiently even during prolonged use. With this upgrade, you can expect to maintain power after multiple hard pulls, unlike the stock setup, which heat soaks after just three.
