VCTR Performance BMW M2/M3/M4 G8X S58 Turbo Inlet Upgrade

Overview

The S58's factory turbo inlets are functional but not optimal for high-demand applications. This CNC billet aluminium inlet replaces the OEM unit with a precisely machined alternative — providing a smoother, more consistent bore from the intake system to the compressor wheel.

Why Upgrade?

• Reduced restriction at the S58 compressor inlet
• CNC machined bore for improved flow consistency compared to cast factory piece
• Improved compressor efficiency at elevated boost demand
• Direct OEM replacement with adaptor for clean installation

Engineering Focus

CNC machined from billet aluminium, this inlet provides tighter dimensional tolerances than the factory cast piece. Includes an adaptor for fitment to the standard S58 inlet location on G8X applications.
