The Nitrous Express 4500 carburetor plate provides a pumpless water-methanol injection interface for carburetors with a 4500 flange, allowing central injection placement for better cylinder distribution. It is designed to integrate with NX pumpless direct-port systems that use a pressurized reservoir and pressure regulator and often utilize braided stainless AN hoses, billet distribution blocks and filtered nozzles.
