This part basically holds your fuel injectors securely in place on the engine. It's not just a clamp, though. It also has O – rings and seals built in to create a really tight connection, preventing fuel leaks. It ensures the injector is positioned precisely so it can spray fuel correctly into the cylinder. It also manages the heat transfer away from the injector. It's a critical part of the fuel delivery system. The fuel injectors need to be perfectly aligned and sealed to get the right amount of fuel into the engine. Without a good nozzle holder, the fuel spray pattern is off, or you end up with fuel leaking into the engine instead of burning properly. It's a small piece, but it affects how efficiently and cleanly your engine runs. If this part fails, you'll probably notice a rough idle, misfires, or a loss of power. You might even smell fuel, which is obviously a concern. It acts like a shield, keeping fuel contained and directing it where it needs to go. A failing seal means lost fuel pressure and an improper air/fuel mixture. It’s something you don’t want to ignore. If you’re handy, it's a reasonably straightforward repair. We can get you the correct nozzle holder assembly, and Fixparts Online has a good selection of them, makes finding the right one easier. Suitable for every driver: Nozzle Holder Assembly (MPN 9431610337) includes a 12-month warranty!
