Nitrous Express 4150 Gasoline (RNC) Nitrous Kit w/15lb Bottle

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 .250 orifice Lightning 250 nitrous solenoid, 8an feed line and a .500 orifice DF5 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. This systems includes a Lightning series fuel solenoid, stainless hard lines to connect the solenoids to the plate, heavy duty relay, switches, stainless bottle brackets and every nut, bolt and electrical connector needed to complete the installation.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.
