Feeding maximum cold air into the twin-turbocharged S68 engine is essential for reducing inlet drag and sharpening the throttle response of the internal combustion unit. Remove the restrictive factory airboxes and upgrade to high-volume Induction Kits or specialized Air Feeds mounted behind the front grilles. For a more subtle enhancement, drop-in high-flow Panel Filters provide a stealthy breathing upgrade. Eliminate airflow turbulence entirely by installing smooth silicone or cast Induction Pipes & Hoses, ensuring the turbochargers on your hybrid M5 are constantly supplied with dense, oxygen-rich air.
