  • Nitrous Express 4500 Assassin Plate Stage 6 Nitrous Kit (50-300HP) w/10lb Bottle
    SKU: 67070-10

    Assassinate the competition with the Assassin plate system. The Assassin is the most technically advanced single stage plate ever designed. The CNC machined design integrates the nitrous and fuel discharge ports into the outer perimeter. The Assassin offers a unique perimeter spray pattern that assures perfect nitrous-fuel distribution. Which in turn solves the problems commonly found on single plane manifolds, particularly small and big block Fords. This new innovation provides superior distribution and outstanding atomization. With no spray bars to sag, split, block airflow, or damage this is the Next Generation in nitrous plate technology.

  • Nitrous Express 4500 Flange Single Entry Crossbar Nitrous Plate Conversion
    SKU: NX613

    The new NX Billet Crossbar nitrous plate systems have just raised the bar in nitrous plate technology. The CNC machined design eliminates round spray bars resulting in excellent atomization and cylinder distribution. With no spray bars to sag, rotate or disrupt airflow, this is truly the Next Generation in cross bar nitrous plate technology. This crossbar nitrous conversion includes a custom solenoid bracket, braided stainless solenoid to plate lines, stainless fittings, nitrous/fuel jets and longer carb studs.

  • Nitrous Express 4500 RNC Conventional Nitrous Plate Kit w/.375in Solenoid w/10lb Bottle
    SKU: 55170-10

    The conventional RNC (Restricted Nitrous Class) systems are the first choice for professional racers that are limited by jet size. These systems feature a CNC billet nitrous plate with enlarged nitrous passages, a .375 in. orifice Lightning nitrous solenoid, 8an feed line and a .500 orifice Lightning 500 bottle valve. The combination of these components results in a very dense liquid nitrous charge which allows the maximum amount of nitrous flow through a certain size jet. Results of these RNC systems are so impressive that you will have to use one to believe it.  Nitrous Express RNC (restricted class nitrous) systems are guaranteed to make the most power per jet size of any system on the market. If you dont make the most horsepower or are not 100% satisfied, NX will gladly refund you 100%.
