CSF Cooling 8109 Twin Charge-Air-Cooler Set for BMW F1X/M5/M6 Crinkle Black

BMW F1X M5 & M6 Twin Charge-Air-Cooler Set - Crinkle Black Finish The S63 4.4L Twin Turbo V8 in the BMW F1X M5/M6 is an absolute monster that responds incredibly well to bolt-on upgrades, larger turbos, and performance tuning. Tuners quickly found that increasing power on the S63 pushed charge air temperatures past the OEM Charge-Air-Coolers' limits resulting in dangerously high Intake Air Temperatures (IATs). Pure turbos approached CSF to develop a Charge-Air-Cooler upgrade that would hold up to the extreme boost levels their turbos upgrades could generate and keep the car's IATs in check. The result was the World's 1st Cast End Tank Designed High-Performance Charge-Air-Cooler Set for the F1X M5/M6. CSF used CFD analysis and testing to create the largest charge-air-cooler that could fit in the factory location. The Top/Bottom, Cross-Flow, Dual-Pass Cores are 28% larger than the factory coolers and offer significant reductions in IATs at increased boost levels. World's 1st Cast End Tank Designed High-Performance Charge-Air-Cooler Set for the BMW F1X M5/M6 Custom Designed CSF Liquid-To-Air Intercooler Core (CFD Analysis and Testing Completed to Ensure Optimal Performance) 28% Increase in Core Size Per Each Charge Cooler Compared to the OEM Charge Air Coolers Top/Bottom, Cross-Flow, Dual-Pass Core Configuration with 2-Stage Water Cooling for Maximum Efficiency and Intake Temperature Reduction Designed with 3D Scanning/Rapid Prototype Technology to Ensure Precise Fitment and Maximum Surface Area Utilization
