S/S Flare Jet - .046

The Nitrous Oxide Systems S/S Flare Jet in .046 inch inner diameter is a precision stainless steel metering jet engineered for nitrous oxide and fuel delivery in high-performance engine systems. This component is essential for tuning the air-fuel ratio in dedicated nitrous oxide applications where precise fuel staging directly impacts combustion efficiency, power output, and engine reliability.

The .046 inch orifice diameter defines the fuel flow rate through the jet under system pressure. Stainless steel construction resists corrosion from fuel exposure and thermal cycling, maintaining dimensional consistency across repeated heat cycles. Flare-style jets are designed for manifold mounting systems where the flare end creates a sealed connection without additional ferrule hardware. Selecting the correct jet size is critical—undersizing restricts fuel delivery and risks lean combustion and detonation, while oversizing floods the fuel charge and reduces power while increasing smoke and engine stress. The .046 specification fits specific system configurations and nitrous oxide kit designs.

This jet is intended for builders and tuners assembling or upgrading nitrous oxide systems on naturally aspirated engines seeking repeatable, controlled power gains. Proper jet selection requires knowledge of system pressure, target horsepower increase, and manifold flow characteristics. NOS jets are precision-manufactured components where dimensional tolerance directly affects metering accuracy, making OEM and quality aftermarket parts the only viable choice for serious builds. Single jets are sold individually, allowing incremental tuning without replacing entire kits.
