The ZEX Race Perimeter Plate Nitrous System is for the serious competitor who wants only the highest performing system on his or her race car. This race kit is fully adjustable between 100 and 450 horsepower. Featuring ZEX Perimeter Injection Technology, nitrous is injected directly into the intake manifold plenum in a 360-degree ring. This smoothes out the distribution and results in a consistent and safe power delivery. The system also benefits from Cryo-Sync Technology to help lower the temperature of the carb and manifold surfaces, creating a cooler, denser nitrous/fuel/air charge entering the engine. The system includes the perimeter plate, a 10 or 15 lb. nitrous bottle with high-flow race valve, -6AN feed lines and fuel and nitrous solenoids.
