All models of the Throttle Body Injector use a variable venturi throttle slide which operates smoothly over teflon glides.  Throttle movement controls air flow and fuel simultaneously.  The patented fuel metering tube atomizes fuel evenly across the entire flow passage.   Fuel is scheduled by the diaphragm controlled regulator which can function in any attitude making the system ideal for aerobatic flight.  Additional features include:

  • Uniform fuel distribution
  • Instantaneous response
  • Low maintenance
  • Aerobatic
  • Few Moving Parts
  • Easy Starting
  • Light Weight
  • Idle Cut-off
