BEAST MODE
MARKET-LEADING SIZE
The IE Race Series Intercooler sets the standard as the largest in its class. Unlike existing options designed to fit B9 2.0T and 3.0T engines, our intercooler is exclusively tailored for the high-powered 3.0T S4 & S5 platform. Utilizing every millimeter of available space, our engineers have optimized the cooling capabilities for any power goal. The result is a massive size measuring 19.4x16.3x4.5", establishing a new benchmark in cooling power for the 3.0L turbocharged engine.

IE FLOW DISTRIBUTION SYSTEM TECHNOLOGY
What is the point of a large intercooler core that can not effectively take advantage of the increased volume and surface area? IE's Flow Distribution System (FDS) places precisely shaped fins inside the end tank to force airflow evenly across the entire core to distribute the heat more effectively and recover faster. When drastically reducing intake air temperatures (IAT) for the most significant power gains possible, IE's FDS technology is the proven cheat code.
REQUIRES IE CHARGE PIPES
DEFEAT HEAT SOAK AND INCREASE AIRFLOW
To seamlessly connect to the intercooler's larger 70mm sized inlet and outlet, our IE Aluminum Charge Pipe Kit (IETPCK6) is required. This combination increases flow and provides an enhances the entire charge air system, delivering high-velocity airflow for unparalleled performance.
IE Charge Pipe Kit is sold separately. If you do not already have this kit installed, add it to your intercooler order using the drop-down menu above.
NO BOOST LEAKS
FULL THROTTLE WITHOUT WORRY
This intercooler is designed for big boost. The end tank inlets/outlets and aluminum charge pipes are CNC machined with flat-stop edge and beveled grooves for a high-friction surface that grips your hoses and locks them in place for good.
STRENGTH
SECURE AND RELIABLE MOUNTING
IE's Race Intercooler features thick-gauge stainless steel mount brackets and reinforced casting mounts for a long life and worry-free operation. All mounting bosses and surfaces have been precision CNC machined and hand-verified for an exact fit.
QUALITY MANUFACTURING
HAND TIG WELDED & PRESSURE TESTED
For maximum quality, finish detail, and outstanding quality, every intercooler is meticulously hand TIG welded by intercooler specialists. Every unit undergoes a strict post-welding multi-point critical inspection and is tested in a leak-down station. This manufacturing level ensures a reliable product ready to install and perform out of the box.
PERFECT FIT
QUALITY IS IN THE DETAILS
Despite its impressive size, our race series intercooler has been designed for a hassle-free installation without any permanent modifications. To ensure a precise fit, IE engineers have employed advanced 3D scanning equipment and rapid prototyping techniques to ensure a tight, yet perfect bolt-in replacement.
DEFEAT HEAT SOAK
Heat soak occurs when the Intake Air Temperature (IAT) generated by the turbo exceed the cooling capacity of the intercooler and passes hot air to the engine. The result is a noticeable loss of power during acceleration and long pulls. Our IE Race Intercooler dramatically increases the core size and useable area of the core with FDS technology to significantly reduced intake air temperatures consistently lower than OEM and competitor intercoolers while increasing flow.
FDS DYNAMICS
FLIR Thermal Equipment and advanced Computational Fluid Dynamics (CFD) software were used to engineer the application-specific FDS fin design. The thermal imagery details air distribution evenly through the core in real time; notice the hot inlet air flowing evenly to the top and across the intercooler core. The better this flow is distributed, the more efficiently the intercooler operates and the speed at which heat is expelled.
FLOW GAIN
To prove the positive effects the intercooler design and FDS system have on airflow and pressure drop, flow testing was performed on the IE Race Intercooler VS. our standard IE FDS Intercooler option. Test results show consistent gains of up to 81.6% more flow over our alternate intercooler offering. This increase details the Race Intercooler's efficiency and capability to provide optimal cooling without negatively impacting airflow demands on any build level.
INTAKE AIR TEMP (IAT)
This graph details the Intake Air Temperature (IAT) over consecutive runs on a Stage 3 Hybrid Turbo S4 at over 650WHP. Three wide-open throttle pulls were made back-to-back on an IE Race FDS Intercooler VS. our standard IE FDS Intercooler (IETPCK1). The result was up to 11.4% lower IAT over our alternate performance intercooler design.
