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

Welcome to our high-flow Turbo Inlet elbows for the S58-powered G8x M2, M3, and M4. Built to improve airflow, throttle response, and overall turbo performance. We’ve crafted each inlet from mandrel-bent 6062-T6 aluminum in 70mm and 63mm sizes, using CNC machining, robotic TIG welding, and a proper velocity stack to keep airflow smooth and unrestricted. It fits perfectly with the stock intake pipes, our MMX Intake Pipe Set (MMR11-1601), or most aftermarket intake setups.

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.
