Electronic fuel injection (EFI) is a high-pressure fuel management system. Just like on today's cars, EFI uses an onboard computer, injector nozzle and multiple sensors to to reliably deliver exactly the right amount of fuel to get the most performance and efficiency out of your engine.

What is the advantage of EFI engine?

EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.
