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.

Nitrous System, Dual 4150/Alcohol, 100-200-300-400-500 HP, No Bottle

Nitrous Express has a nitrous system for people with carbureted vehicles whose high performance philosophy is "too much is almost enough." Their Pro Power plate systems crank out power in spades, from a 100 to as much as a 500 hp increase over stock at the wheels. The heart of these systems is the "Next Generation" Phase 3 distribution plate, which has no spray bars to sag, split, or disturb the airflow into the manifold. Race fuel is required for increases above 150 hp.

The kits come complete with:
• Nitrous bottle and stainless steel mounting brackets
• Solenoids
• Relay
• Supply line and fittings
• Switches
• Wiring
• Mounting hardware
