Nitrous Express 60040-05 4150 Gemini Twin-Discharge Stage 6 Nitrous Plate System Kit with 5 lb Bottle (50-300HP)

The Nitrous Express 60040-05 Gemini Stage 6 is a complete, bolt-on nitrous oxide plate system designed for carbureted engines using a standard 4150-flange carburetor. Engineered as the most technically advanced single-stage nitrous plate available, the Gemini system delivers precise nitrous and fuel distribution through its patented direct-port spray pattern — eliminating the distribution problems commonly associated with single-plane intake manifolds, especially on small- and big-block Ford applications.

Unlike traditional plate systems that rely on spray bars, the Gemini design eliminates spray bar sag, splitting, airflow restriction, and damage — representing a true next-generation approach to nitrous plate technology. Superior atomization and even charge distribution are the direct result of this innovative layout.

• Gemini 4150-flange nitrous plate with direct-port spray pattern
• Stage 6 jetting package — calibrated for 50, 100, 150, 200, 250, and 300 HP power levels
