Description
The IE Race Series FDS Intercooler is the largest and most efficient intercooler solution available for the B9/B9.5 Audi SQ5 3.0T. Designed exclusively for the 3.0T platform—not shared with 2.0T applications—this upgrade uses every millimeter of space behind the front grille to deliver massive gains in cooling, airflow, and reliability. When pushing your SQ5 to the limits, whether with bolt-ons or a full Stage 3 setup, this intercooler ensures intake air temperatures (IATs) stay consistently low—eliminating heat soak and maximizing power output.
Note: This is Box 2 of 2. A complete kit requires the purchase of both IETPCZ1-Box 1 and IETPCZ1-Box 2. This box includes the Race FDS Intercooler core and high-flow silicone hoses.

Massive Cooling Power
Measuring an impressive 19.4 x 16.3 x 4.5 inches, the IE Race Intercooler boasts a core volume 280% larger than the factory intercooler. This massive increase in surface area and airflow capacity means cooler, denser intake air reaches your engine—supporting sustained performance under prolonged high-load conditions. Whether you're accelerating hard or doing repeated pulls, you'll maintain optimal power levels.
FDS: Flow Distribution System
IE's proprietary FDS internal fin design distributes air evenly across the full surface area of the core, maximizing cooling efficiency. Unlike competitors, who may increase size without addressing internal airflow dynamics, FDS ensures that the entire core is utilized, resulting in significantly improved cooling and faster heat recovery.
No Leaks, No Worries
The end tank inlets and outlets are CNC machined with beveled grooves and flat-stop edges to lock hoses securely in place. Combined with reinforced aluminum charge pipes (sold separately), this design prevents boost leaks, even under extreme pressure, making the intercooler system reliable for aggressive driving and high-boost applications.
Race-Grade Manufacturing Standards
Every IE Race Series Intercooler is hand TIG-welded by experienced craftsmen and undergoes rigorous quality control including post-weld inspections and pressure testing. The result is a performance product that not only performs flawlessly but also delivers long-term durability under the most demanding conditions.
