Nitrous Express Gasoline 50-300HP Jet Pack for Dual Holley Nitrous Plate Kit

NX Jets are manufactured on CNC equipment, and are guaranteed to be within .0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi-stepped outlet allow turbulence free flow with no restrictions.

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.

While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
