Forge Motorsport Chargecooler Radiator and Expansion Tank Upgrade for Audi S5 3T

For the Audi S5 3.0 litre Supercharged, 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 coolant temperatures lower but also reducing the reduction times in "heat soaked" situations
