For the Audi S4 B8 and S5 B8 3.0 litre Supercharged, we have developed an uprated Charge Cooler Radiator and Expansion Tank kit as an evolution of our S5 kit.
There are four variations of chargecooler for the S4 B8 and B8.5 chassis. In order to purchase the correct one for your car, you will need to look at the current setup you have fitted from the factory: if you have one or two chargecooler radiators as standard, and if your car is fitted with ADS (Audi dynamic steering).
Please refer to this PDF to ascertain which is the correct part for your car.
This FMCCRAD2 kit is for the S4 and S5 with twin factory chargecoolers and no ADS cooler
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.
This product holds 4L of coolant or 1.056 US liquid gallon

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.
