Real temperature drop. Real performance.
Independently proven to drop intake air temperatures by 10 C versus the OE heat exchanger on a B58 car running a Pure Turbos Stage 2 upgrade, this CSF charge cooler water radiator keeps IATs consistent pull after pull. Lower IATs mean denser air, more oxygen and more reliable power. Hotter air increases the risk of knock, so the ECU pulls timing and reduces power. Improve cooling to maintain power and reliability on your B48 or B58 BMW.
