Nitrous Express 4500 Assassin Plate Stage 6 Nitrous Systems

Nitrous Express 4500 Assassin Plate Stage 6 nitrous systems for alcohol fuel deliver a 100 to 300 hp rating, are offered with or without a bottle, and feature one of the most technically advanced single stage plates ever designed—the Assassin.

Nitrous Express CNC-machined 7/8 in. thick Assassin plates integrate nitrous and fuel discharge ports into the outer perimeter, producing a unique spray pattern that assures perfect nitrous-fuel distribution. This solves the problems commonly found on single plane manifolds, particularly small and big block Fords, and creates superior distribution and outstanding atomization with no spray bars to sag, split, or block airflow. Select the Assassin Stage 6 system without or with the preferred bottle size.

Systems include:

* Jetting for 100, 150, 200, 250, and 300 hp
* Billet aluminum and carbon fiber lightning solenoids
* Heavy-duty 40 amp relay
* 4 AN supply line
* Billet aluminum Y-fittings
* Stainless braided solenoid-to-plate lines
* Bottles available in 10, 12, and 15 lb. capacities
* Systems with bottle come with stainless bottle brackets and Lightning 500 bottle valve
* Fits standard Dominator flange carburetors
