BMW M3 Performance Air Intake by Dinan for G8x M3/M4 (2021–2026), Gloss Carbon Fiber. A premium cold‑air upgrade that refines response, sound, and engine bay presence.
Centered on a single plenum that replaces the factory split ducts, this system adds volume and straightens flow to the S58. Enlarged airboxes are fed by the factory grilles plus carefully validated lid cutouts, creating a controlled semi‑open path that amplifies induction tone without hurting temps or pressure. High‑flow cotton filters and carbon construction reduce restriction, aid turbo efficiency, and provide headroom for modified builds. Gloss 2x2 twill finish. Note: OEM M4 CSL and M3 CS strut brace not compatible.
