Integrated Engineering Race FDS Intercooler System For Audi B9/B9.5 S4 & S5 IETPCK5

Built for enthusiasts demanding the highest performance from their Audi 3.0T platform, the IE Race FDS Intercooler System sets a new standard for cooling efficiency. Exclusively engineered for the B9/B9.5 Audi S4 and S5, this intercooler offers a 280% increase in core volume over stock, drastically reduces intake air temperatures (IATs), and virtually eliminates heat soak, even under the most demanding conditions.

With a core size of 16.3 x 19.4 x 4.5 inches, low-pressure drop design, and IE's proprietary Flow Distribution System (FDS), this intercooler is purpose-built for Stage 3+ power levels while maintaining OEM-like fitment. When paired with the required IE Aluminum Charge Pipe Kit (IETPCK6), you unlock seamless 70mm inlet/outlet airflow integration and unmatched charge system efficiency.

Key Features:

• 280% Larger Core Volume Than Stock
  Delivers industry-leading cooling capacity to support even the most aggressive builds

• IE Flow Distribution System (FDS)
  Internal fin structure ensures even airflow across the entire core, maximizing thermal efficiency and power output

• Record-Setting Size
  Massive 16.3 x 19.4 x 4.5" bar-and-fin core fully utilizes available space in the B9 engine bay

• Low-Pressure Drop with 70mm Inlets/Outlets
  Designed for high-flow efficiency without restricting boost response

• Required IE Aluminum Charge Pipes (IETPCK6)
  Ensures perfect 70mm connection and optimized charge air routing

• CNC-Machined & Leak-Free Design
  Precision flat-stop and beveled hose connections prevent boost leaks at high pressures

• Heavy-Duty Mounting
  Reinforced stainless steel brackets and thick aluminum castings for extreme durability

• Hand TIG Welded in the USA
  Expert craftsmanship and post-weld pressure testing ensure a perfect, reliable product every time

• True Bolt-On Fitment
  Installs in the factory location with no permanent modifications required

Performance Gains:

• Up to 11.4% Lower Intake Air Temperatures
  Compared to the standard IE FDS intercooler on a 650+ WHP Stage 3 hybrid turbo S4

• Up to 81.6% Increased Airflow
  Over IE's standard FDS model, demonstrating unmatched cooling and pressure drop efficiency

• Eliminates Power-Robbing Heat Soak
  Maintains consistently low IATs across repeated acceleration runs and high-load scenarios

Perfect OEM-Style Fitment Without Sacrifices

Despite its massive size, the IE Race Intercooler is designed to bolt directly into place using factory-style mounts. Thanks to advanced 3D scanning and prototyping, no cutting or permanent modifications are required. Every mounting boss is precision CNC-machined and verified for a perfect fit with factory and IE charge pipe systems.

Installation Notes:

• IE Charge Pipe Kit (IETPCK6) is required for installation

• Install time:

  • ~2–3 hours (if IE charge pipes are pre-installed)

  • ~5 hours (full intercooler + charge pipe installation)

• Designed for B9/B9.5 Audi S4 & S5 3.0T models only (not compatible with B9 2.0T applications)

Applications:

• Audi B9/B9.5 S4 (3.0T)

• Audi B9/B9.5 S5 (3.0T)

• Engine Compatibility: 3.0L TFSI Turbocharged V6 (Single Turbo – EA839)
