The Nitrous Express Assassin plate conversion for 4500 flange, Stage 6, brings the Assassin perimeter-discharge design to 4500-style intakes. As a Stage 6 conversion, it supplies the CNC-machined perimeter ports and flange compatibility needed to convert an existing 4500 intake to Assassin-style nitrous distribution, improving atomization and cylinder balance while keeping the original intake architecture.
