Nitrous Oxide Systems

No forced induction system delivers power on demand faster than nitrous. When the bottle is open and the solenoid fires, nitrous oxide injection adds oxygen and fuel simultaneously — producing a power increase that turbos and superchargers simply can't match for cost-per-horsepower or installation simplicity. This collection covers complete nitrous injection systems and every supporting component: bottles, solenoids, injectors, purge kits, controllers, distribution blocks, nozzles, jets, and all hardware for street and strip applications where every tenth counts.

Complete nitrous kits are the fastest path to a functional system. Wet kits inject both nitrous and supplemental fuel simultaneously through a dedicated nozzle, making them compatible with virtually any induction system — carbureted or EFI. Dry kits inject nitrous only and rely on the engine's existing fuel system to compensate, making them simpler to install but requiring a fuel system capable of delivering the additional fuel demand. Plate systems distribute nitrous evenly across all cylinders via a spacer plate between the carburetor or throttle body and intake manifold —

the preferred approach for carbureted applications. Direct port systems inject nitrous and fuel at each individual cylinder for maximum distribution uniformity and the highest power potential.

Nitrous bottles are available in a range of capacities — from compact 2.5 lb bottles for tight installations to 15 lb and larger units for extended runs and high-shot applications. Bottle heaters and pressure gauges ensure consistent system pressure for repeatable power output across varying ambient temperatures. Purge kits clear vapor from the nitrous line before activation, ensuring the system delivers liquid nitrous from the first hit — critical for consistent, repeatable performance on the track.

Solenoids are the heart of the nitrous system — controlling the flow of nitrous and fuel with precision timing. High-flow solenoids support larger shots without flow restriction. Jets and nozzles determine the nitrous and fuel flow rates and are the primary tuning variable in any nitrous system. Jet changes allow power output to be adjusted in increments without modifying the rest of the system. Distribution blocks ensure equal nitrous delivery across multiple nozzles on direct port systems.

Nitrous controllers and window switches add a layer of safety and tuning capability — activating the system only within a defined RPM window, ramping nitrous delivery progressively to reduce shock load on the drivetrain, and integrating with ignition retard systems to protect the engine under nitrous activation. These are not optional on serious applications — they're the difference between a reliable power adder and an engine-damaging detonation event.

This collection serves drag racers, street/strip builds, and performance enthusiasts who want maximum power on demand without the complexity and cost of a full forced induction system. Nitrous is legal for street use in most jurisdictions when the bottle valve is closed — verify local regulations before use on public roads.

Nitrous system installation is within reach for any experienced builder. Wet plate systems are the most straightforward — typically a half-day install with basic tools. Direct port systems require more time and precision. Any nitrous application should be supported by a proper ignition timing retard strategy, a fuel system capable of meeting the increased demand, and an engine in good mechanical condition with appropriate compression for the intended shot size.
