The ARM Motorsports S58 Intake System is designed to deliver the highest possible airflow and drastically improved turbo induction sound for BMW’s G-series S58 platform. By utilizing the shortest and most direct path between the high-flow filters and the turbochargers, this intake significantly enhances turbo response, throttle feel, and overall engine character. No cutting, drilling, or trimming is required, making installation quick and fully reversible.

At the core of the system are oversized 3.5-inch turbo inlets constructed from high-temperature, 6-layer reinforced silicone. These inlets provide maximum airflow capacity while maintaining OEM-level durability. Paired with inverted high-flow multimedia filters offering a combined surface area of 290 cubic inches, the intake ensures abundant, unrestricted airflow to both turbos.

The ARM S58 Intake uses wrinkle-black aluminum inlet pipes that connect directly to the turbos through precision CNC-machined adapters. Each adapter is engineered to match the size and shape of the front and rear turbo inlets individually, providing superior sealing and fitment compared to the OEM plastic connectors. The adapters retain the OEM C-clip mounting method for secure and straightforward installation.

This intake system is the ideal upgrade for enthusiasts seeking both performance and sound—bringing out the signature turbo character of the S58 engine while supporting stock, Stage 1, and Stage 2 power levels.
