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.

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.

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.

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.

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.

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.

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.
