Nitrous Express GM EFI Dual Stage Jet Pack

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.

Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.

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.

Images are supplied by the manufacturer and may be generic. 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. For assistance or clarification, please contact customer support.
