The AMS Performance BMW G8X M2/M3/M4 S58 Intake System with Carbon Fiber Lids is engineered to maximize airflow, power, and throttle response for the twin-turbocharged S58 engine. This system features a massive 3.5" carbon fiber intake tube, smooth-flowing 4-ply silicone couplers, and oversized cast aluminum turbo inlet elbows that are up to 128% larger than the OEM components. The result is dramatically increased airflow and significantly reduced intake restriction.

The premium enclosed carbon fiber lids provide a refined, high-end appearance while maintaining excellent airflow and filter protection. Magnetic fasteners allow for quick and easy access during maintenance. On the dyno, this intake system delivers gains of up to +86 WHP at peak and an average increase of +66 WHP above 5000 RPM. These improvements provide a broader, more consistent powerband with stronger mid-range torque and exceptional top-end performance.

Dry filter media ensures long-term reliability, easy cleaning, and consistent airflow, while the precision-engineered components guarantee a perfect OEM-like fit. Extensive flowbench and real-world testing confirm reduced pressure drop, improved turbo efficiency, and balanced airflow across both banks for predictable tuning and consistent performance. From daily driving to competitive track use, this intake system delivers measurable, repeatable gains.

Professional calibrators and racers validated the system through independent and track testing, demonstrating stronger turbo response, reduced restriction, and improved high-RPM power delivery. Whether you value performance, aesthetics, or both, the AMS Performance S58 Intake System with Carbon Fiber Lids offers a premium upgrade that enhances engine sound, efficiency, and overall driving experience.

The enclosed carbon fiber design not only looks exceptional but also supports optimal airflow characteristics, ensuring the S58 engine receives the volume of air required to perform at its highest potential.
