NOS Nitrous Oxide Solenoid
NOS Nitrous Oxide Solenoids: Precision Flow Control from the Industry Leader
When it comes to nitrous oxide delivery, the solenoid is the critical gatekeeper between your bottle and your engine. Nitrous oxide solenoids act as electronically controlled valves — using an electromagnet to open a plunger and regulate nitrous flow into the intake system with split-second precision. Choose the wrong one, and you're leaving power on the table or worse, risking engine damage. Choose a solenoid from NOS (Nitrous Oxide Systems), and you're trusting the brand that has defined performance nitrous for decades.
Why NOS Solenoids Stand Apart
NOS nitrous solenoids are built with a proprietary plunger material that resists swelling, paired with a strong stainless steel base for durability under the demanding pressures nitrous systems operate at. Every NOS solenoid features the brand's signature stainless steel base with directional in/out markings stamped in — a simple but meaningful quality indicator that racers and enthusiasts have come to trust.
Across the lineup, NOS solenoids use PTFE plunger puck material in their nitrous-side units for outstanding sealing and longevity, while fuel-side solenoids utilize FKM rubber plunger pucks for chemical compatibility and a reliable seal. The blue powder-coated housings on nitrous solenoids and red on fuel solenoids make identification intuitive during installation and maintenance.
The NOS Solenoid Lineup: Something for Every Build
NOS offers an extensive range of solenoid lines to suit everything from entry-level street kits to all-out race builds. The lineup includes the Cheater, Powershot, Pro Shot, Pro Bigshot, Super Bigshot, and Sniper — each engineered for a specific performance tier and horsepower range.
- Sniper Solenoid: The Sniper nitrous solenoid supports up to 250hp, delivering solid NOS-quality performance in a compact package — ideal for street and light track use.
- Cheater Solenoid: Features a PTFE plunger and 3/32" orifice, capable of supplying up to 250hp with optimum flow and operation.
- Super Powershot Solenoid: A step up in capacity, featuring a 5/64" orifice and PTFE plunger rated to handle up to 175hp flows with dependable response.
- Pro Bigshot Solenoid: The flagship of the NOS solenoid range, the Pro Bigshot features a massive .250" orifice housed in a lightweight, clear anodized billet aluminum base for maximum flow in extreme applications. Its pressure-balanced design dramatically reduces power draw, requiring only 4–6 amps during operation — a major advantage in multi-stage setups. At just 3.5" tall and 1.63" in diameter, it installs cleanly even in tight multi-solenoid configurations.
Built for Reliability, Engineered for Performance
Nitrous solenoids must handle pressures well in excess of what fuel solenoids encounter, and NOS engineers its solenoid line accordingly. The stainless steel bases resist corrosion, the large orifice sizes ensure unobstructed flow, and the color-coded housings help eliminate wiring and plumbing confusion in the engine bay. For builders who want to go further, NOS also offers rebuild kits, replacement coils, and solenoid brackets to keep their setup in peak condition over the long haul.
Whether you're refreshing an existing nitrous system or building a new one from scratch, NOS nitrous oxide solenoids deliver the flow, reliability, and race-proven engineering that serious performance enthusiasts demand.
