AIR-TO-AIR ADVANTAGE
Your factory 2.9TT water-cooled intercooler relies on a severely undersized core volume of only 1,870cm³ (114ci³) and shared engine coolant to regulate air intake temperatures. Even in completely stock form, spirited and normal driving leads to significant rises in air temperatures, resulting in power reduction. The cooling benefits of water are not enough to compensate for the tiny intercooler size, coupled with the increased water weight and heat demands on the radiator.

The iE intercooler adopts a traditional air-to-air design, divorcing the core from engine coolant. This strategic shift substantially increases core volume to 18,500cm³ (1129ci³), providing an extensive surface area for efficient heat dissipation. This separation delivers unmatched cooling for even the most serious builds, less water weight, and allows the factory radiator to focus solely on keeping the drivetrain cool.

iE FDS TECHNOLOGY
What's the use of a large intercooler core if it can't efficiently harness the increased volume and surface area of the core? IE's Flow Distribution System (FDS) places precisely shaped fins inside the end tank to ensure uniform airflow across the core surface area evenly. This advanced design element enhances heat distribution and enables quicker recovery. When it comes to significantly reducing intake air temperatures (IAT) for maximal power gains, IE's FDS technology stands as the proven cheat code.

POWER RESULTS
Power testing reveals consistent impacts on horsepower and torque. The graph provided details the power gained over the stock intercooler in back-to-back testing under identical conditions. By effectively lowering Intake Air Temperatures (IATs), controlling pressure drop, and maximizing flow, the iE intercooler delivers significant power improvements across the entire RPM range, boasting gains of 36HP and 35ft-lbs of torque!

NO BOOST LEAKS
This intercooler is designed to handle high boost levels and ensures reliable operation. The inlet and outlet are CNC machined with flat-stop edges and beveled grooves to provide a high-friction surface that securely grips the boost hoses in place. This fine attention to detail prevents potential boost leaks and ensures long-term reliability.

STRENGTH
The provided thick-gauge stainless steel mount brackets and reinforced casting mounts are meticulously engineered to ensure longevity and worry-free operation. Every mounting boss and surface undergoes precision CNC machining and meticulous hand verification to guarantee an exact fit. Despite its substantial size, the intercooler seamlessly retains the factory crash bar, prioritizing safety without compromising performance.

QUALITY MANUFACTURING
To ensure maximum quality, meticulous attention to detail, and outstanding craftsmanship, each intercooler undergoes precise hand TIG welding by skilled intercooler specialists. Following welding, every unit undergoes rigorous post-welding multi-point critical inspections and thorough testing in a leak-down station. This stringent manufacturing process guarantees a reliable product ready to install and performs flawlessly right out of the box.

PERFECT FIT
Despite its impressive size, this intercooler has been meticulously designed for a precise fit. iE engineers utilize state-of-the-art 3D scanning equipment and rapid prototyping techniques, guaranteeing a snug yet perfect installation.

Note: Fitment has been confirmed for North American RS5 only.
