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.

If you have a carbureted vehicle and you're on a budget or are just getting started, Nitrous Express Stage 6 nitrous systems could be the ideal beginning point. They're tunable to deliver power boosts in six graduated increments, from 50 hp all the way up to 300. That means you can pick one of the lower increases for an engine that's close to stock, and then ramp things up later on when you add forged pistons.

Systems include:
• Nitrous distribution plate
• Supply hose and fittings
• Solenoids
• Switches
• Wiring
• Jets
• Mounting hardware
• Race fuel required for increases above 150 hp
