When you're pushing more power from your Audi B9 S4 or B9 S5, managing intake air temperatures becomes increasingly important. The Spool Performance Race Intercooler is engineered to provide significantly greater cooling capacity than the factory intercooler, helping maintain consistent intake temperatures and reliable performance during repeated pulls, spirited driving, and track use.

Featuring a massive high-density bar-and-plate core, high-flow cast aluminum end tanks, and CNC-machined inlet and outlet connections, this intercooler is designed to improve heat dissipation while maintaining efficient airflow under high boost. With nearly twice the cooling capacity of the factory unit, it provides the thermal headroom needed for both stock and upgraded turbocharger applications.

Increased Cooling Capacity for the 3.0L TFSI

The factory intercooler can become a limiting factor as power levels and boost pressure increase. Repeated acceleration generates significant heat, which can cause intake air temperatures to rise and lead to heat soak and inconsistent performance.

Spool Performance addresses this limitation with a substantially larger intercooler core designed to absorb and dissipate more heat. The result is improved temperature control and more consistent performance, particularly during repeated acceleration and demanding driving conditions.

The high-density bar-and-plate construction provides increased surface area for heat transfer while maintaining efficient airflow through the core.

Nearly Twice the Factory Cooling Capacity

The Spool Performance Race Intercooler offers nearly twice the cooling capacity of the factory intercooler. This increased capacity provides greater thermal efficiency and helps the turbocharged 3.0L TFSI engine maintain lower intake temperatures under load.

Lower intake temperatures can help support:

• More consistent horsepower and torque
• Improved performance during repeated pulls
• Reduced heat soak
• Better intake temperature control
• Increased thermal headroom for higher boost levels
• More consistent operation during track and spirited driving

For modified B9 S4 and S5 builds, the additional cooling capacity provides valuable support as airflow and boost demands increase.

High-Flow Cast Aluminum End Tanks

The intercooler features high-flow cast aluminum end tanks engineered to distribute air evenly across the core.

Efficient airflow distribution helps maximize the available cooling surface area while minimizing unnecessary turbulence and pressure loss. This design works together with the large intercooler core to provide efficient charge-air cooling without compromising airflow through the system.

The result is a cooling solution capable of supporting both factory turbochargers and upgraded hybrid turbo applications.

CNC-Machined Inlet and Outlet Connections

To provide reliable performance under high boost pressure, the Spool Performance Race Intercooler utilizes fully CNC-machined inlet and outlet connections.

These precision-machined connections are designed to provide accurate alignment and a secure seal between the intercooler and charge-air system. This helps reduce the risk of boost leaks while providing the durability required for high-performance applications.

Built for Stock and Modified Audi Builds

The Spool Performance Race Intercooler is designed to support a wide range of B9 S4 and S5 configurations.

Whether you're running the factory turbocharger or planning a larger hybrid turbo upgrade, the increased cooling capacity provides additional thermal headroom for demanding applications.

It's particularly well suited for vehicles running:

• Performance ECU tuning
• Increased boost pressure
• Upgraded turbochargers
• Repeated high-load driving
• Spirited street use
• Track applications

By improving charge-air temperature management, the intercooler helps create a more consistent foundation for additional performance modifications.

Direct Bolt-On Installation

Despite its larger cooling capacity, the Spool Performance Race Intercooler is designed as a direct replacement for the factory intercooler.

The system utilizes the factory mounting locations and does not require cutting or permanent vehicle modifications. This makes it a straightforward upgrade for owners looking to increase intercooling capacity while maintaining a clean installation.

Professional installation is recommended to ensure proper fitment, connection, and system sealing.

Durable Performance Construction

The Spool Performance Race Intercooler combines a high-density bar-and-plate core with cast aluminum end tanks and CNC-machined connections to create a durable solution for high-performance driving.

Its construction is designed to withstand the increased temperatures and boost pressures associated with modified turbocharged applications while providing consistent cooling performance over repeated heat cycles.
