Unlock the True Potential of Your S58 Engine
The BMW G8x platform is a masterpiece of modern performance, but the factory intake system leaves performance on the table. At Samurai Performance, we offer the ultimate solution: the Genuine GruppeM Ram Air System. Designed specifically for the S58 twin-turbo engine, this is not just an intake—it is a complete aerodynamic overhaul for your engine bay.
The Ram Air Advantage
Unlike standard open-filter kits that suck in hot air from the engine bay, the GruppeM system utilizes a proprietary "Ram Air" design. By channeling high-velocity, cool air directly from the front kidney grilles into dual, sealed carbon fiber filter housings, this system creates a positive pressure effect (boost) as vehicle speed increases. The result is a denser oxygen charge, sharper throttle response, and consistent power delivery that doesn't fade due to heat soak.
A Symphony of Carbon & Sound
Crafted in Japan from hand-laid carbon fiber, the intake ducts are designed to maximize volume while retaining a lightweight, rigid structure. The gloss carbon finish transforms the G8x engine bay into a work of art. Beyond the visuals, this system uncorks the S58’s vocal cords—delivering an aggressive induction roar and audible turbo spool that the factory muted.
