AMS Performance Cold Air Intake for BMW G80 M3, G82 M4, and G87 M2

Description

he AMS Performance G8X S58 Intake System with carbon fiber lids and magnets transforms the way your BMW M2 (G87), M3 (G80/81), or M4 (G82/83) breathes. Engineered from the ground up to maximize airflow and throttle response, this system replaces the restrictive stock intake with oversized components including a 3.5″ carbon fiber tube and precision cast aluminum turbo inlet elbows up to 128 % larger than OEM. The enclosed carbon lids use magnetic fasteners for effortless filter access and a refined engine bay look. Dyno testing has shown up to +86 WHP peak gains over stock and an average of +66 WHP above 5000 RPM, broadening the S58’s powerband while retaining smooth, predictable power delivery. Dry media filters ensure reliable filtration and easy maintenance, while the plug-and-play design makes installation straightforward.
