The Nitrous Express 4150 Gemini Stage 6 alcohol nitrous kit (less bottle) is a Gemini plate configured for alcohol use and fits standard 4150 flange carburetors. Its direct-port pattern improves distribution and atomization and avoids spray-bar drawbacks on single-plane manifolds. Stage 6 includes jetting for 50–300 HP, Lightning solenoids, a heavy-duty 40A relay, stainless bottle brackets, an extra 4AN supply line and a limited lifetime warranty.
