The release of the 1990 Subaru Justy  was the last car sold that used carburetors. The beginning of the 90's welcomed the fuel injection system -- first central fuel injection and then multi-port or 'sequential' fuel injection system. The benefit of modern day fuel-injection systems is the precise measurements of fuel and the precision with which it is injected.
| How It Works |
|
- The fuel pump provides the injector with pressurized fuel.
- The injector is an electronically controlled valve that when fuel passes through the nozzle it is atomized.
- The fuel injector sprays or 'injects' at the intake valve.

Fuel Injectors versus Carburetors:
Carburetors are still championed by many car enthusiasts. Carburetors frequently surpass electronic fuel injection (EFI) in horsepower. Most people don't want to spend time tuning a carburetor when they can have a computer do it for them. The fine tuning is responsible for the carburetors exceptional performance, so if you love cars and like to tinker with parts, the carburetor is always a superior choice. But if you are a carb person, you already knew that.
