Description
Maximize the performance of your Audi RS6 or RS7 with the IE FDS Intercooler System, engineered for the C8 4.0T platform. Featuring a 63% increase in core volume, exclusive FDS (Flow Distribution System) technology, and dual carbon fiber air guides, this twin intercooler system significantly reduces intake air temperatures (IATs) and eliminates heat soak. Whether you’re running a Stage 1 tune or hybrid turbos, this upgrade ensures consistent, safe power delivery under all driving conditions.
Key Features:
-
63% increase in core volume for maximum cooling
-
Up to 31.87% reduction in intake air temperatures (IATs)
-
12.66% improvement in airflow for enhanced throttle response
-
Proprietary FDS technology for even air distribution and reduced pressure drop
-
Dual carbon fiber air guides deliver cool ambient air directly to the cores
-
TIG-welded, hand-built construction for long-lasting durability
-
Direct bolt-on installation with no cutting required
-
Compatible with stock or upgraded turbo systems
Built for Demanding Power Applications
The factory intercoolers on the RS6 and RS7 are undersized and prone to heat soak, even at stock power levels. IE’s performance intercoolers deliver a substantial increase in thermal capacity, providing 657.4in³ of core volume per side, compared to the stock 401.6in³. This ensures your V8 engine maintains consistent power output with reduced temperature-related timing and boost reduction.
Advanced FDS Core Design
IE’s exclusive Flow Distribution System (FDS) utilizes strategically engineered internal fin structures to channel airflow evenly across the entire intercooler core. This eliminates uneven cooling, reduces pressure drop, and ensures reliable charge air cooling across the powerband.
Carbon Fiber Air Guides for Maximum Efficiency
Twin carbon fiber air ducts are included to route cold air from outside the front bumper directly into the intercoolers. This design isolates the charge air from hot engine bay temperatures, maximizing cooling efficiency under high-performance conditions.
Real-World Proven Gains
Dyno testing with multiple consecutive gear pulls showed intake air temperatures were reduced by up to 31.87% compared to the factory intercoolers, with an average reduction of 21.9%. The result is cooler, denser air, allowing the engine to sustain more power without timing or boost reductions. Real-world performance is expected to be even better due to natural airflow at speed.
Premium Construction Quality
Each intercooler is hand-welded by skilled technicians using TIG welding methods and is pressure tested for leaks before shipping. Manufactured from high-grade materials, these units are designed for long-term reliability under extreme conditions.
Easy Installation
