The CSF top-mount charge-air-cooler for 2014+ BMW M3/M4 (F8X) increases core volume by about 60% over the factory unit to reduce intake air temperatures under repeated high-load use. Designed as a drop-in with OEM-style quick-connect water ports and sensor fittings, the crinkle-black powder-coated unit uses cross-flow, dual-pass and two-stage water cooling to improve heat dissipation and maintain power during extended performance driving.
