Does the Audi 2.8 require matching when replacing fuel injectors?

[RicardoMarie]

Audi 2.8 can directly install the new fuel injectors without matching. The relevant introduction of fuel injectors is as follows: Definition of fuel injectors: A fuel injector itself is a normally closed valve (a normally closed valve means that the valve remains closed when there is no input control signal; while a normally open valve remains open when there is no input control signal), controlled by the up and down movement of a valve needle to open or close the valve. Working principle of fuel injectors: When the ECU issues a fuel injection command, its voltage signal causes current to flow through the coil inside the fuel injector, generating a magnetic field to lift the valve needle, thereby opening the valve to allow fuel to spray out from the injector nozzle. The biggest advantage of fuel injection is the precise control of fuel supply, ensuring the engine maintains the correct air-fuel ratio under any condition. This not only keeps the engine running smoothly but also ensures that the exhaust emissions comply with environmental regulations.
