The AMS Performance BMW G8X M2/M3/M4 S58 Intakes are engineered to deliver maximum airflow, power, and response for your twin-turbocharged S58 engine. Featuring a massive 3.5” carbon fiber intake tube, and smooth transition 4-ply hump hose silicone couplers, this system allows air to flow effortlessly into the turbos for unmatched performance. Our oversized cast aluminum turbo inlet elbows are up to 128% larger than stock, and provide a direct, unobstructed path to the compressor wheels, while your choice of enclosed carbon lids or open-top configuration lets you tailor the look, sound, and airflow to your preference. On the dyno, these intakes delivered an astonishing +86 WHP peak gain over stock and an average of +66 WHP above 5000 RPM, giving the G8X platform a broader and more consistent powerband all the way to redline. The dry filter media ensures long-term reliability and easy maintenance, and installation is simple thanks to precision fitment and industry-leading instructions. Unlock the full potential of your M2, M3, or M4 with the AMS Performance G8X S58 Air Intakes — where performance engineering meets carbon fiber perfection.

The Power of Focused Engineering
AMS Performance is an engineering company first, and our Snailworks Engineering Team approached the development of the BMW G8X M3/M4 Air Intakes with a single mission: maximize airflow and efficiency without compromise. Using advanced modeling, flowbench testing, and dyno validation, our engineers designed a system that dramatically reduces restriction and pressure drop across the entire intake tract. The result is a 128% larger cross-sectional area compared to OEM pipe, allowing the turbos to breathe freely for improved compressor efficiency, and consistent power increases all the way to redline.
To match both performance and aesthetics, the Snailworks team created two distinct variations: a premium carbon fiber lid version with magnetic fasteners for effortless filter servicing, and an open-top configuration featuring a powder-coated trim piece and premium stainless hardware for the ultimate in airflow and induction sound. Whether you choose the refined carbon enclosure or the aggressive open design, every component was engineered for precision fitment, strength, and real-world performance. This engineering-first approach ensures the AMS Performance G8X Air Intakes deliver measurable gains on the dyno — and a clear advantage on the road or track.
