MAD BMW G8X M3 M4 AIR INTAKE (FRONT FACING) MAD-5049

MAD 3.5" High-Flow Intake System for BMW M3 & M4 (G-Chassis, S58 Engine) – Unleash the Sound & Performance

Upgrade your BMW’s performance and sound with the MAD 3.5" High-Flow Intake System, engineered specifically for the S58-powered G80 M3 and G82 M4. This intake system is designed to replace the restrictive OEM airbox, delivering more power, sharper throttle response, and aggressive turbo sound that enthusiasts crave.

Hear the Turbo. Feel the Power.

With its oversized 3.5” piping and dual inverted cone air filters, this intake system allows significantly more airflow, reducing turbo spool time and enhancing engine response.
