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
Please Note: In line with our policy to constantly review, revise, and improve our product range, the appearance of the product you receive may differ from the one advertised.
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.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
