Ultimate cooling upgrade for BMW F8X platforms — M2 Competition, M3 and M4

Take control of intake temperatures with the CSF auxiliary chargecooler pre-radiator for BMW F80, F82 and F87 M2 Competition. This premium alloy cooler is engineered for demanding fast-road and track use, delivering exceptional thermal efficiency, consistent power, and reliable heat management on stock and tuned setups. Ideal for anyone searching for an intercooler water radiator, water-to-air chargecooler pre-rad, coolant pre-cooler or upgraded cooling pack for the S55-powered F8X.
