Description Fitment

Unleash the full airflow potential of your BMW S58 engine with the MAD High Flow Turbo Inlets. Designed for performance-focused enthusiasts, these CNC billet inlet pipes replace the restrictive factory units to improve airflow, turbo response, and overall efficiency. Whether you are running the stock intake or an aftermarket intake that uses the factory connection size, these inlets are a direct fit.

Precision machined from solid billet aluminum, the MAD S58 High Flow Inlets feature smooth internal transitions and optimized geometry to reduce turbulence before the turbochargers. This results in faster spool, improved throttle response, and stronger mid to high RPM performance without sacrificing reliability or fitment.
