A true 100% New Bosch Injector. Injectors have to endure 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. With the Hardened Alloy Body, the Twister Series injector will last much longer than an OEM injector. Don't be fooled by cheap knock-offs or Remans they will not last!

Lets talk about the nozzles. The nozzle has 6-8 holes at a certain angle. 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 this Twister Series Injectors with a 21% gain average and a 28% gain high.
