For the Audi S5/S4 3.0 litre Supercharged B8.5 Chassis ONLY, we have developed an uprated Charge Cooler Radiator and Expansion Tank kit. This kit is highly recommended for either those in warm climates who wish to maintain performance, or specifically for tuned engines where the boost has been increased from standard on the Eaton Supercharger using software re-calibration, a reduction pulley or a combination of both. To maximise the cooling efficiency we use an alloy fast thermal transfer radiator core which is 640 x 440 x 42mm. This has proven very effective in both keeping chargecooler temperatures lower but also reducing the recovery times in "heat soaked" situations

I needed a heat exchanger for my Audi S4 B8.5, and didn't want to settle for a "do-it-yourself" product. I knew of Forge's reputation and a friend recommended this kit as high-quality and complete. It's installed now, and is fantastic - great quality, well-thought-out installation, and has done wonders for the supercharger heat. All that and it looks like it should be a stock option. I highly recommend this kit.
