About this part

Product Details

This Nitrous Express 4150 Gemini Stage 6 Alcohol Nitrous Kit comes with everything you need to get started. You'll receive the Gemini direct-port plate, a composite nitrous bottle, stainless steel bottle brackets, a heavy-duty 40-amp relay, limited lifetime warranty Lightning solenoids, and an extra 4AN long supply line. This kit is specifically designed for alcohol fuel systems and fits standard 4150 flange carburetors.

The Gemini plate is a technically advanced single-stage system. Its unique direct-port pattern ensures perfect nitrous and fuel distribution, solving common issues found on single-plane manifolds, especially for small and big block Fords. This design offers superior distribution and outstanding atomization without spray bars that can sag, split, or block airflow. It's truly the next generation in nitrous plate technology.

This Stage 6 system includes jetting for 50, 100, 150, 200, 250, and 300 horsepower increases, giving you flexibility for different performance goals. The included composite bottle is lighter than traditional steel bottles, and the Lightning solenoids are built for reliability with a limited lifetime warranty. Remember, this system is not CARB approved and cannot be shipped to California.
