The Nitrous Express Assassin single-stage plate for 4500 flange with 12lb bottle brings the Assassin’s CNC-machined perimeter discharge together with an included bottle and is rated up to 750 hp. The outer-perimeter nitrous and fuel outlets promote superior atomization and balanced cylinder distribution on single-plane manifolds, avoiding problems caused by traditional internal spray bars that can sag or restrict airflow.
