About NOS – Nitrous Oxide Systems

Few names carry as much weight on the drag strip as NOS (Nitrous Oxide Systems). NOS was born in the late 1970s when two dedicated racers perfected the science of nitrous oxide injection for automotive performance — transforming what had been a closely guarded secret of wartime aviation into a reliable, accessible power-adder for the street and strip. Since then, NOS has become the most recognized name in nitrous, trusted by enthusiasts from weekend bracket racers to professional competitors chasing record-breaking passes.

The brand's early years were defined by hands-on testing, dyno development, and a commitment to proving that nitrous could be both safe and effective. That groundwork paid off: NOS was involved in some of drag racing's most celebrated milestones, including milestone runs in the Pro Mod class during the 1980s. Today, NOS is part of the Holley Performance family, giving it access to world-class engineering resources while retaining the focused identity and deep catalog that made it legendary.

A Complete Ecosystem of Nitrous Components

What sets NOS apart is not just a single product, but a complete, engineered ecosystem of nitrous components. At the heart of any NOS setup are its Nitrous Oxide Solenoids — available in a range of series including the Cheater, Powershot, Pro Shot, Pro Bigshot, Super Bigshot, and Sniper lines, ensuring there is a solenoid matched to every power level and application. These solenoids use a proprietary plunger material designed to resist swelling, housed in a durable stainless steel body for long-term reliability.

The foundation of every NOS system is the Nitrous Oxide Bottle — precision-engineered aluminum cylinders available in multiple sizes to hold the N2O charge at the correct pressure. Because bottle pressure is critical to system performance, NOS pairs its bottles with purpose-built Nitrous Oxide Bottle Heaters that use thermostatically controlled heating elements to maintain the optimal 900–950 psi operating range regardless of ambient temperature.

For carbureted and EFI builds alike, NOS offers a broad selection of Nitrous Oxide Plates and Nitrous Oxide Injector Plates — low-profile billet or die-cast aluminum spacers that mount between the carburetor or throttle body and the intake manifold, delivering a precise, metered charge of nitrous and fuel to the engine. Available in 4150 and 4500 flange configurations as well as sandwich-style designs for modern EFI intakes, these plates are backed by years of laboratory research and dyno and drag strip testing.
