Premium Craftsmanship: Hand TIG-welded, pressure tested, and verified for leak-free operation
-
Fitment: Confirmed for North American B9 RS5 models
Air-to-Air Advantage: More Cooling, Less Compromise
The stock RS5 intercooler relies on a compact water-to-air design with shared engine coolant and a minimal core size of only 1,870cm³. This limits its thermal efficiency and leads to power loss during spirited or extended driving.
The iE Air-to-Air Intercooler System dramatically increases core volume to 18,500cm³, freeing the intake system from the limitations of the stock cooling setup. This design shift reduces water weight, lightens thermal load on the radiator, and offers significantly improved IAT control—perfect for stock or high-performance builds.
Exclusive FDS Internal Fin Technology
A large intercooler core is only as effective as its airflow management. IE’s Flow Distribution System (FDS) utilizes specially engineered internal fins to evenly distribute airflow throughout the core, avoiding heat saturation at the center and maximizing cooling across the full surface. This technology significantly improves temperature recovery, lowers IATs, and increases horsepower—especially in high-performance and tuned applications.
Built to Withstand High Boost and Demanding Conditions
The iE intercooler is designed to handle aggressive builds and high boost levels without compromise. Machined connection points feature anti-slip edges and beveled grooves to secure hoses and eliminate the risk of boost leaks. Mounting hardware includes robust stainless steel brackets, and the design retains compatibility with the factory crash bar for added safety and structural integrity.
Precision Engineering for a Perfect Fit
Designed using 3D scanning and rapid prototyping, the iE RS5 Intercooler is a direct bolt-on upgrade that fits precisely into the factory location. No permanent modifications are required, and installation is hassle-free for professionals and experienced enthusiasts alike.
