About this part

Product Details

This is the Nitrous Express 4150 Gemini Pro-Power Nitrous Kit, designed to add significant horsepower to vehicles equipped with standard 4150 flange carburetors. This system offers a unique approach to nitrous injection, aiming for precise fuel and nitrous distribution directly into each cylinder. It's engineered to solve common issues found with older plate designs, especially on single plane manifolds used in many performance Ford engines.

The Gemini plate system is built with a direct-port pattern that ensures each cylinder receives an equal amount of nitrous and fuel. Unlike systems with spray bars that can sag or obstruct airflow, this plate design offers a cleaner path for intake mixture. It comes with jetting options for 100, 200, 300, 400, and 500 horsepower increases, giving you flexibility as you tune your engine. The kit includes a composite 15lb nitrous bottle, heavy-duty 40-amp relay, stainless steel bottle brackets, and an extra long 4AN supply line.

Included with the kit are Lightning solenoids, which carry a limited lifetime warranty, and the system is available for alcohol applications. This is a comprehensive package for those looking to significantly boost their engine's power output. Please note that this kit is not CARB approved and cannot be shipped to California.
