Shopping for Fuel Injector
How Much Does a Fuel Injector Replacement Cost?
A replacement fuel injector can cost you anywhere between $20 and $810 on parts alone. Labor costs can add anywhere between $180 and $225 to the final bill. The exact amount varies according to factors like your vehicle’s make and model as well as the rates in your area.
What Is a Fuel Injector?
The electronic equivalent of the carburetor, fuel injectors spray fuel into the engine’s cylinders or intake manifold. They are controlled by the engine control unit, which makes sure the injectors release enough fuel to create the optimal air-fuel mixture for the engine’s current load.
While fuel injectors are relatively simple and sturdy, they remain vulnerable to electrical and mechanical failure. Injectors can develop clogs, internal leaks, or getting stuck in either a closed or open position. The problems caused by a bad fuel injector can reduce your vehicle’s performance or even damage the engine.
