The iE Air-To-Air Intercooler System for your Audi RS5 2.9TT is meticulously engineered to optimize flow, efficiency, and volume, delivering unmatched cooling capabilities. A remarkable 997.36% increase in volume compared to the stock intercooler ensures efficient heat dissipation and minimizes pressure drop for enhanced performance.

iE VS. STOCK

The factory water-cooled intercooler for the 2.9TT relies on a small core volume and shared engine coolant, leading to significant temperature rises and power reduction during spirited driving. In contrast, the iE intercooler features a traditional air-to-air design with a 10X larger core volume of 18,500cm³, providing superior cooling performance and reducing water weight demands on the radiator.

iE FDS TECHNOLOGY

IE's Flow Distribution System (FDS) technology ensures uniform airflow across the core surface area, enhancing heat distribution and enabling quicker recovery. This advanced design significantly reduces intake air temperatures (IAT), maximizing power gains and performance.

PERFECT FIT

Despite its impressive size, the intercooler is precisely designed for a snug and perfect fit. Utilizing state-of-the-art 3D scanning equipment and rapid prototyping techniques, iE engineers guarantee precise installation without compromising performance.

WORRY-FREE STRENGTH

Thick-gauge stainless steel and aluminum mount brackets and reinforced casting mounts ensure longevity and worry-free operation. Every mounting boss and surface undergoes precision CNC machining and meticulous hand verification, retaining the factory crash bar for safety without compromising performance.

PREMIUM MANUFACTURING

Each intercooler undergoes precise hand TIG welding by skilled specialists, followed by rigorous post-welding inspections and testing to guarantee reliability and flawless performance.

AVERAGE IAT GAIN

The graph compares Intake Air Temperature (IAT) gains between the factory intercooler and the iE air-to-air design. Each line represents the average IAT over six consecutive 12-second pulls in a single gear on a Stage 1 RS5. The results consistently show lower and stable IATs with the iE intercooler across every pull.

It's important to note that this testing was conducted on a hub dyno. Real-world conditions, with the vehicle in motion and airflow passing through the intercooler, are expected to yield even more impressive cooling results.

POWER GAINS

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

While some power enhancements can be attributed to denser and cooler charge air, most gains result from reduced timing and boost pull due to lower intake temperatures, further confirming the exceptional efficiency of the air-to-air design.
