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.

Water/Methanol Injection System, Gas, Stage 2, Universal, Boost, Kit

You'd be crazy to throw water into a gas tank and expect to get anywhere—but power and torque can be increased if you inject it into the incoming air charge with Nitrous Express water/methanol injection systems. Cooling the air charge allows for increased timing and the resulting performance benefits. These versatile units have a wide-open throttle switch for naturally aspirated vehicles and an adjustable boost-activated switch for forced induction models. Nitrous Express systems inject a fixed amount of fluid when the WOT switch or boost is activated—and continues until the switch opens again. They reduce intake temperatures and the need for timing retard when used with nitrous. Stage II kits come complete with a high-output pump, 3 qt. reservoir, nozzle, boost activated progressive controller, switch, hardware, and detailed instructions. Water has always been used to cool down motors, but with Nitrous Express water/methanol injection systems … it'll be heating things up!
