The Nitrous Express Gemini Stage 6 single-stage plate kit (fits standard 4150 flange carburetors) is an advanced direct-port plate that improves nitrous and fuel distribution and atomization. By eliminating spray bars it avoids sagging or airflow disruption on single-plane manifolds, including small and big block Fords. Stage 6 includes jetting for 50–300 HP, Lightning solenoids, a heavy-duty 40A relay, stainless bottle brackets, extra 4AN supply line and a limited lifetime warranty.
