Audi S4 B8 and S5 B8 3.0 TFSI Charge Cooler Radiator and Expansion Tank kit
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 S5 B8 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 FMCCRAD4 kit is for the S4 and S5 with twin factory chargecoolers and a factory 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.
