Audi S4 B8 / S5 8T 3.0 TFSI Forge radiator kit

For the Audi S5 / S4 3.0 litre Supercharged (B8.5 chassis only), Forge has 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 they 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.
