Nitrous Jets

Nitrous jets are the precise metering orifices at the heart of any nitrous oxide injection system. They control the flow of fuel and nitrous into the intake tract, directly determining the air/fuel ratio and resulting horsepower gain. Whether you are fine-tuning an existing plate, fogger, or direct-port setup, selecting the correct jet size is critical for safe and repeatable performance.

Our collection covers a range of jet sizes to support common tuning needs. While manufacturer jetting charts provide a baseline, actual flow is influenced by bottle pressure, ambient conditions, and engine characteristics. We strongly recommend starting with the specified jetting and only making small adjustments while monitoring wideband oxygen sensor readings and spark plug condition.

  • Precision-machined orifices for consistent flow characteristics
  • Available in multiple diameters to dial in fuel and nitrous delivery
  • Suitable for both wet and dry nitrous system configurations
  • Essential for safe, incremental tuning of your nitrous setup

Always consult your system's installation manual and a reliable tuning reference. A dyno session with experienced tuner is the best way to validate your jet selection and avoid engine damage.
