PRODUCT DESCRIPTION
Conventional RNC (Restricted Nitrous Class) systems are the top choice for professional racers that are restricted by jet size. These systems feature a CNC-machined nitrous plate with enlarged nitrous passages, a .375" orifice Lightning nitrous solenoid, an 8AN feed line, and a .500" orifice Lightning 500 bottle valve. The combination of these components results in a very dense liquid nitrous charge allowing for maximum nitrous flow through a given jet size. The results from these RNC systems are so impressive you will have to try them to believe it. Nitrous Express RNC (Restricted Class Nitrous) systems guarantee the most horsepower per jet size of any system on the market. If you don't make the most horsepower or are not 100% satisfied, NX will refund 100%.

8AN feed line
Custom 6AN to 4AN line from N2O solenoid to plate
.375" N2O Solenoid
