Nitrous Express 55040-10 RNC 4150 Gasoline Plate Nitrous Kit with 15 lb Bottle

The Nitrous Express 55040-10 is a conventional RNC (Restricted Nitrous Class) nitrous oxide system designed for the 4150 4-barrel carburetor on gasoline-fueled engines. This system is the first choice for professional racers competing in classes that limit jet size, delivering maximum nitrous flow and power output within those restrictions.

At the heart of this system is a CNC billet nitrous plate with enlarged nitrous passages, paired with a .178" orifice nitrous solenoid and an 8AN feed line. Together, these components produce a very dense liquid nitrous charge, allowing the maximum possible nitrous flow through a given jet size. The result is more horsepower per jet size than any competing system on the market — a claim Nitrous Express backs with a 100% satisfaction guarantee.
