Description
The Mishimoto MMAI-G80-21CFG is a purpose-built carbon fiber cold air intake engineered specifically for the S58B30-powered BMW G8X chassis. Built with dual carbon fiber airboxes and intake tubes, this system was developed using 3D printing, CAD modeling, and flow bench testing to cut intake restriction by 13 percent on the driver-side tract and by up to 22.8 percent on the passenger-side tract compared to the factory setup.
As a complete air intake system, this Mishimoto cold air intake replaces the restrictive factory panel filters with dual high-flow oiled air filters made from multi-layered cotton, boosting filter surface area and airflow while additional wheel-well ducting feeds cooler ambient air into each airbox. The solid 3K twill-woven carbon fiber construction, available in matte or gloss finish, resists heat soak far better than plastic factory components while amplifying turbocharger spool and bypass valve venting for a more aggressive intake tone under acceleration. It’s designed to run safely on a stock ECU tune, so drivers researching cold air intakes, intake filters, or air intake filter upgrades for their BMW M-car get real flow gains without requiring a tune.
Vehicle Applications
This intake is a direct-fit application for BMW G8X chassis vehicles (G80, G82, G83, and G87) equipped with the S58B30 3.0L twin-turbo inline-six. Coverage includes the BMW M3 Base (2021–2024, 2026), M3 Competition (2021–2026), M3 Competition xDrive (2022–2026), and M3 CS (2024); the BMW M4 Base (2021–2026), M4 Competition (2021–2023, 2025–2026), M4 Competition Heritage (2023), M4 Competition xDrive (2022–2026), M4 CS (2025–2026), and M4 CSL (2023); and the BMW M2 Base (2023–2026), M2 Coupe (2023–2024, 2026), and M2 CS (2026).
