A fuel injector comprises a valve and atomising nozzles; several of these work together in a car's fuel injection system. The job of the fuel injector is to dispense the fuel into the engine efficiently. If yours needs replacing, browse the extensive range below.
Fuel injectors were a very useful development from the old carburettor system as they improve the fuel efficiency of cars while also reducing pollution. For internal combustion to take place in a car's engine, the car needs both oxygen and fuel. There is an air-intake system to deliver the oxygen and it is the fuel injectors that deliver the fuel. Since the fuel supply is limited and the oxygen supply is inconsistent, the engine needs to dispense just the right amount of fuel to mix with the oxygen in order to be as efficient as possible - this is what the fuel injectors do.
Fuel injectors can become clogged so it's worth cleaning them every now and then. If you need new ones, it is recommended to replace the whole set at the same time. We stock high-quality fuel injectors for every type of car.
