⚠ Not for cars with active grille shutters
Some late-model B9.5 cars have active grille shutters, and this intercooler does not fit them. Check your car before ordering.
KEEP YOUR CHARGE AIR COOL
Add a tune or a bigger turbo to your B9 and the factory intercooler is the first thing to give up. The iE FDS Intercooler drops in where the stock unit lives with a core nearly twice the size, so your S4, S5, SQ5, A4 or A5 keeps making power long after stock would have heat soaked. Raw aluminum or black. Complete kit. One afternoon with a standard toolset.
THE ONE AND ONLY FDS
Most intercoolers let charge air take the easy path straight through the middle of the core. The iE Flow Distribution System uses precisely shaped fins cast into the inlet plenum to spread air evenly across the entire core. The whole core works, so intake air temperatures drop further than with any competing unit, and you keep the power.
ELIMINATE HEAT SOAK
Heat soak is what happens when the heat you make outruns the cooling you have. You feel it as fading power after a long pull or a few back-to-back runs. A much bigger core put fully to work by FDS keeps intake temps consistently lower than stock and competing intercoolers, pull after pull.
PRECISION ENGINEERED
iE engineers used Computational Fluid Dynamics to shape the end tanks and the FDS fins for minimum pressure drop and maximum flow. The end tanks are cast, then machined, then TIG welded to a dense bar and plate core measuring 21.25 x 17.5 x 2.5 inches. Every intercooler is pressure tested on our in-house station before it ships.
NO BOOST LEAKS
The inlet and outlet are fully machined so your hoses seal and stay put under boost. The intercooler end tanks connect to the factory hoses, and the inlet tank has a 1/8 NPT bung cast in, ready for water-methanol injection.
PERFECT FIT. COMPLETE KIT.
This is a true OEM replacement. CNC machined mount points let you reuse the factory mounting locations, so it installs like a factory part with no cutting, trimming or modification. The kit includes the intercooler, install brackets, and every bolt, washer and clamp you need.
