This little piece is responsible for actually spraying the fuel into the engine's cylinders. It takes the pressurized fuel and atomizes it – basically turns it into a really fine mist. The nozzle itself has tiny holes, and that’s what creates the spray pattern. It's not just dumping fuel in there, it’s creating a consistent, finely dispersed cloud for better combustion. Think of it as one of the key players in getting power out of your engine. The engine control unit tells the injector when to spray, and the nozzle determines how it sprays. It works with the fuel injector body to deliver the right amount of fuel at the right time, so the engine runs smoothly and efficiently. Everything from acceleration to fuel economy relies on these nozzles working correctly. Well, if a nozzle gets clogged or worn, the spray pattern gets messed up. You might get too much fuel, not enough, or an uneven spray. That leads to a lot of problems – rough idling, misfires, loss of power, poor fuel economy, and even engine damage long – term. You’ll notice if it's bad, generally. The engine will run noticeably rough, or the check engine light will come on. It acts like a shield protecting the engine from incomplete combustion. We’ve got a good selection of these at Fixparts Online, if you’re looking to replace yours, and it’s often a good idea to replace all of them at the same time to avoid issues down the road. Better than the rest: Nozzle (MPN 5641020) includes a 12-month warranty!
