Injectors are available in 4 power levels:

. Injectors are exposed to extremely high pressures(around 30,000 psi) and therefore will wear out. Most people will start to notice a lack of power, mileage suffering, hard starts, white smoke, or excessive black smoke when injectors are going out. Don't be fooled by cheap knock-offs or Remans they will not last!

The nozzle has up to 8 holes at a certain angle and pattern. Depending on the amount of holes, size and configuration you can have different results with different nozzles. We have patented of own nozzle called the Twister Series. We have done an ISO 9001 Fuel Consumption Test on his Twister Series Injectors with a 21% gain average and a 28% gain high.
