This assembly basically does two jobs. The nozzle itself is the part that sprays the fuel into the engine, it’s precision – made to atomize the fuel into a fine mist for efficient combustion. The holder, as the name suggests, securely keeps the nozzle in place on the engine, and also provides the sealing surfaces to prevent fuel leaks and ensures it's properly aligned. It also has the electrical connection for the injector. Think of it as a critical part of your engine’s fuel delivery system. Fuel gets pumped to the injectors, and this nozzle and holder assembly is the final step before the fuel enters the cylinder to create power. Each cylinder has its own injector assembly, so it’s a vital component for each one. It’s responsible for getting the right amount of fuel, at the right time, into the engine. Well, if this fails, you’ll definitely notice. A failing nozzle can cause a rough idle, misfires, poor fuel economy, and even a complete loss of power. The holder is important because if it cracks or the seals fail, you’ll get fuel leaks, which is obviously a safety hazard and can damage other engine components. A worn or damaged assembly just won't deliver the fuel properly. You’ll notice if your engine is running poorly, or if you smell fuel where you shouldn't. It acts like a shield, keeping everything sealed and working efficiently. We carry a good selection of these at Fixparts Online, and getting a new one can often resolve a lot of engine performance issues.
