Description
The BMW S55 motor is a remarkable engine, yet its cooling system, comprising the charge pipe, aftercooler, and heat exchanger, has been identified as a potential weak point. The Active Autowerke Aftercooler Kit offers a premium upgrade designed to enhance performance and mitigate heat soak issues, ensuring your F80 M3, F82 M4, or F87 M2 Competition runs at its best.
This aftercooler is meticulously crafted from high-grade aluminum, engineered to outperform the stock unit in any driving scenario, from daily commutes to extreme racing conditions. While the factory cooler is designed for a specific power target, many enthusiasts have pushed their S55 beyond this limit, leading to increased intake air temperatures that can trigger the ECU to downgrade performance.
Key Features:
- Enhanced Cooling Efficiency: The tube and fin core is specifically designed for the S55, maximizing cooling in a compact package.
- Billet Machined End Tanks: Ensures even distribution of coolant throughout the aftercooler cores, enhancing performance and reliability.
- High Precision Construction: CNC machining and TIG welding prevent pressure loss and minimize weight, making for a quality bolt-on replacement.
- Aesthetic Appeal: Carbon fiber coating on the top of the aftercooler provides a premium look to match its performance capabilities.
Silicone Charge Pipes: The Active silicone charge pipes replace the stock plastic pipes that are prone to hairline fractures, which can lead to unwanted leaks and reduced power. These 5-layer silicone hoses maintain structural integrity under boost, preventing heat soak and ensuring consistent airflow. Each kit includes necessary adapters and stainless hose clamps for a seamless installation.
High-Performance Heat Exchanger: Often overlooked, the heat exchanger plays a critical role in maintaining performance. The included high-performance heat exchanger prevents heat soak even after extensive use—allowing for sustained power and efficiency. Unlike the stock system, which can heat soak after just a few pulls, this upgraded heat exchanger remains effective for multiple runs.
This three-piece cooling kit is the ultimate solution for your F8X S55, designed for enthusiasts who demand the best in performance and reliability.
