MMX Performance G8X M2 / M3 / M4 (S58) Turbo Inlet Elbow Set

Big gains, clean fit. Our G8X Turbo Inlet Elbows unlock serious flow for your S58.

Welcome to our G8x Turbo Inlet Elbows, developed specifically for the S58-powered BMW M2, M3 and M4. This direct-fit solution is designed to significantly improve airflow and turbocharger efficiency, giving you both performance and reliability.

We’ve built the inlets using mandrel-bent 6062-T6 aluminum, with 70mm and 63mm outer diameters for smooth, unrestricted airflow. Each part is CNC machined, mandrel formed and robotically TIG welded to ensure perfect fitment, consistent quality and strength under high-boost loads. A velocity stack at the inlet helps maintain laminar airflow into the turbo, improving spool and throttle response.

The tubing maintains a constant diameter all the way to the turbo opening, removing the usual restrictions found in factory setups. It’s fully compatible with OEM intake pipes, our own MMX Intake Pipe Set (MMR11-1601) and most popular aftermarket systems. Whether your M-Car is stock or modified, you’ll feel the difference straight away.

Each inlet is hand polished, anodized in MMX Titanium, finished with a laser etched MMX logo. We include all the required hardware in the box for a straightforward, bolt-on installation.
