4150 Restrictor Plate Systems

4150 Plate System

4150 system offers a two-piece modular design. This two-piece spacer design offers a far more precise way to machine the part. This avoids the mismatched machining caused when trying to machine the slot to the plate nesting pocket. The two plates are sealed with a Viton O-ring that creates a perfect seal once the carburetor is fastened to the intake manifold. The two-piece design offers a much more economical option if the system is damaged.

Each Plate System Includes:

  • 4150 Two Piece Modular Spacer  (Spacer 0.75" overall Height)
  • 20 Restrictor Plates selected for your application
  • Compatible with PerformAIRE and RaceWORKS prediction systems
