CSF B58 | B48 Charge Cooler Water Radiator - BMW M140i | M240i | 340i | 440i Finish:Silver RKP Composites has emerged asThe CSF Charge Cooler Water Radiator AKA Heat Exchanger is the most technologically advanced on the market. The tuning potential for the charge cooled M1 240i, 1 2 3 420i and 1 2 3 425i is huge. However, once boost levels are increased the charge air temperature increases which is due to compressed air heating up. The stock cooling system works okay on a stock car but once boost levels are increased and more heat is introduced it begins to struggle.
