Product Details

The Nitrous Express NP677 is a replacement nitrous plate designed specifically for 4500-series carburetors. This Assassin-series plate provides a direct upgrade path for racers running large-format carburetors who need precise nitrous distribution.

Key Features:

  • Designed for 4500-series carburetor flange pattern
  • Assassin series design for optimized nitrous distribution
  • CNC-machined construction for precise tolerances
  • Plate-only configuration allows custom system building or replacement
  • Compatible with Nitrous Express Assassin plate systems

This plate-only option is ideal for racers who need a replacement component or are building a custom nitrous system. The 4500 flange pattern fits Dominator-style carburetors and provides the foundation for a complete wet or dry nitrous setup when combined with appropriate jets, nozzles, and solenoids.
