DESIGN DETAILS
GOODBYE HEATSOAK
Heat soak occurs when the Intake Air Temperature (IAT) generated by the turbo exceeds 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. The 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.
MARKET-LEADING SIZE
The iE Race Series Intercooler sets the standard as the largest in its class. Unlike existing options designed to fit both 2.0T and 3.0T engines, our intercooler is exclusively tailored for the high-powered 3.0T SQ5 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 B9 3.0L turbocharged engine.
- 280% volume increase over stock intercooler
- 55% volume increase over standard IE FDS Intercooler
STAY COOL WITH FDS
What is the point of such a large intercooler if it can't take advantage of the massive isurface area? iE's Innovative Flow Distribution System (FDS) places precisely shaped fins inside the end tank to force airflow evenly across the entire core. This technology distributes heat more effectively, recovers faster, and drastically reduces intake air temperatures (IAT) for the most significant power gains possible. iE FDS technology is the proven cheat code.
NO BOOST LEAKS
Go 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.
STRONG & SECURE
iE's Race Intercooler integrates a thick-gauge steel crash beam 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
Every intercooler is meticulously hand TIG welded by iE's intercooler specialists to ensure outstanding quality and finish detail. 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.
PERFORMANCE DATA
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 TEMPS
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 the iE Race FDS Intercooler VS. our standard iE FDS Intercooler (IETPCK1). The result was up to 11.4% lower IAT over existing performance intercooler designs.
| RUN 1 | RUN 2 | RUN 3 | AVERAGE | |
| IAT Decrease | 10.72% | 10.15% | 11.48% | 10.79% |
INSTALL DETAILS
INSTALL GUIDE
Install your new intercooler kit (and charge pipes) without any permanent modifications or installation hassles. The install process is involved, yet straightforward with basic tools.
- Install time with charge pipe pre-installed: About 2-3 hours
- Install time with new charge pipes: About 5 hours
REQUIRES CHARGE PIPES
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 enhances the entire charge air system with 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.
PERFECT FIT
Quality is found 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.
