The injectors are controlled by the engine's electronic control unit (ECU) and ensure the correct air-fuel mixture, helping to improve engine performance, fuel efficiency, and emissions control. Their flawless operation is critical to expected vehicle performance and reliability.

Fuel injectors are an important part of a vehicle's air and fuel delivery system. Along with the throttle, fuel tank, pump, and filter, they play a vital role in delivering fuel precisely to the engine for optimal combustion.
