A1390704000 Mercedes-Benz Passenger INJECTION VALVE

Basically, a fuel injector is an electronically controlled valve that sprays fuel into the engine. It takes fuel under pressure and atomizes it—turns it into a really fine mist—so it mixes with air for combustion. Modern engines usually have one injector per cylinder, though older ones might have fewer. They're precision parts, really. They measure out just the right amount of fuel needed for how the engine is running at any given moment. These are absolutely critical for the engine to run. They’re part of the fuel delivery system, taking fuel from the tank and getting it into the cylinders where it's burned to create power. Think of it like this: the fuel pump gets the fuel to the injectors, and the injectors are the ones actually delivering it into the engine. Without them, nothing happens. They work with the engine’s computer, taking signals about engine load, speed, and other things to decide how much fuel to inject. If a fuel injector fails, you’ll notice it. You’ll likely get poor fuel economy, rough idling, misfires—the engine might feel like it’s stumbling. You could also see a loss of power. Sometimes, a failing injector can even cause the engine to not start at all. They are under a lot of stress from heat and fuel pressure, so they do wear out over time. You can find replacements pretty easily, we even stock a good range at Fixparts Online, but getting a bad one replaced before it causes bigger problems is always a good idea. They really act like a shield protecting the engine from running lean, and when that shield fails, things can go downhill quickly. A warranty you can count on: Fuel Injector (MPN A1390704000) has a 12-month guarantee!
