 Dual Perimeter Plate Nitrous System

Until recently, nitrous systems for dual 4-barrel intake manifolds have consisted of a couple of plates bolted under the carburetors, equipped with crude brass spray bars to inject nitrous and fuel into the intake charge. The ZEX™ system has nitrous and fuel outlets placed at 24 injection points around the perimeter of the intake manifold’s plenum. This distributes nitrous oxide and fuel perfectly and guarantees the most horsepower possible. With another ZEX™-developed technology called Cryo-Sync™, super chilled nitrous is injected through the ZEX™ plates to cool the carbs and intake before being injected into the engine. Finally, ZEX™ Airflow Enhancement™ Technology creates an intense low pressure area under the carbs while you spray, helping to smooth and increase the airflow into the engine.

Patented, Revolutionary Perimeter Plate Technology:

Cryo-Sync™ Technology

The ZEX™ Perimeter Plate routes the nitrous through a set of internal passages before spraying it into your engine. During this circulation process, the nitrous temperature drops to -127 degrees below zero! This cryogenic phenomenon effectively turns the plate into an ultra-efficient Cryo-Sync™, cooling your carburetor and intake manifold for additional power.

Airflow Enhancement™ Technology

The ZEX™ Perimeter Plate has been designed to inject the nitrous at an optimized angle, toward the center of the intake plenum. In addition to ensuring proper cylinder distribution, this ZEX™- developed technology creates a pocket of intense low pressure just below the carburetor while the nitrous is being sprayed. This low-pressure area enhances airflow into your engine, which further improves power gains.

Perimeter Injection™ Technology

Unlike traditional nitrous kits, the ZEX™ Perimeter Plate employs multiple injection points to create a perfectly atomized blend of fuel and nitrous. This mixture is then fired directly into the center of the intake plenum, ensuring equal dispersal between cylinders. By optimizing cylinder-to cylinder distribution, ZEX™ Perimeter Injection™ Technology generates maximum power without sacrificing engine safety.
