?Key Features:

• Massive 4-Inch Inlet Diameter
  One of the largest on the market, maintaining consistent cross-sectional area to maximize airflow velocity and volume.

• CFD-Optimized Flow Path
  The entire inlet geometry has been carefully simulated and validated using CFD software to eliminate turbulence, improve efficiency, and ensure peak performance under load.

• Premium Aluminum Construction
  High-strength cast aluminum with T6 heat treatment delivers durability and temperature stability under extreme conditions.

• Modular Turbo Flange System
  Includes 3 interchangeable CNC-machined flanges:

  • 56.5mm (OEM)

  • 63mm

  • 66mm
    Easily adaptable to stock and most hybrid turbo upgrades.
