The Mishimoto performance air intake for 2021+ BMW G8X M3/M4 is a complete bolt-on kit that reduces intake restriction and enhances turbocharger response. Rotational-molded thermoplastic airboxes supply cool air via additional wheel-well ports, and dual high-flow oiled filters increase filtration area. The system lowers airflow resistance for improved throttle response and provides a more aggressive intake sound while fitting without major modification.
