BMW E60 M5 / E63 M6. The E60/E63 M5/M6 intake system is designed to make a positive impact for the whole driving experience. By taking advantage of aerodynamic principles and using computational fluid dynamics to optimise the airflow, we have engineered an intake system which delivers on all fronts - sharpened throttle response, more torque and power, improving driveability and of course, an amazing V10 induction sound.
