H414WK D421 Hengst Fuel filter

Basically, this thing cleans the fuel. Fuel isn’t always perfectly clean when it comes out of the tank, you get dirt, rust, and other particles building up over time. The filter catches all that gunk before it gets to your engine. It’s a pretty simple idea, but crucial. It’s designed to allow fuel to flow through, but stop anything solid. It sits inline between your fuel tank and your engine. Think of it as the last line of defense for clean fuel. The fuel pump sends the fuel to the filter, then the clean fuel flows onward to the engine where it's actually used. It’s usually found somewhere under the vehicle, near the fuel tank or along the fuel line, though the exact location varies depending on the make and model. A clean fuel supply is vital for your engine to run right. The fuel injectors are really precise little nozzles, and even tiny particles can clog them up. A clogged fuel injector leads to poor performance – rough idling, loss of power, and even engine damage in the long run. The fuel filter acts like a shield, protecting those injectors and keeping everything running smoothly. You’ll notice if it’s going bad because your engine might start to hesitate, lose power when accelerating, or just run generally rough. It’s a relatively inexpensive part to replace, and it can save you a lot of money and headaches down the road. You can often find a good selection of them at places like Fixparts Online, and they're usually fairly straightforward to swap out yourself if you're comfortable doing a bit of wrenching.
