Product details
The Gemini plate system is the most technically advanced single stage plate ever designed. The unique direct-port pattern assures you perfect nitrous-fuel distribution. It solves problems commonly found on single plane manifolds, particularly small and big block Fords. This new innovation provides superior distribution and outstanding atomization. With no spray bars to sag, split, block airflow, or damage this is truly the 'Next Generation' in nitrous plate technology. This Stage 6 system includes jetting for 50, 100, 150, 200, 250 & 300HP and includes a COMPOSITE nitrous bottle, limited lifetime warranty Lightning solenoids, heavy duty 40 amp relay, stainless bottle brackets, and extra 4AN long supply line (Race Hose). Fits standard 4150 flange carburetors. The Gemini plate system is the most technically advanced single stage plate ever designed.
