Injectors are available in 5 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, suffering mileage, hard starts, white smoke, or excessive black smoke when injectors are starting to fail. With the Hardened Alloy Body, the Twister Series injector will last much longer than an OEM injector. We have a 300,000 mile/3 year warranty on our Twister Series injectors. Don't be fooled by cheap knock-offs or Remans that don't last! Buy Twister Series injectors and feel the difference!
