079905234B Volkswagen ROTOR

The rotor’s main job is to send high – voltage electricity to the spark plugs. Think of it like the final link in the chain, taking the power from the ignition coil and getting it where it needs to go – to create that spark inside the engine. It essentially distributes the spark to each cylinder in the correct firing order. It’s part of your ignition system, obviously. Specifically, it sits on top of or beside the distributor (on older vehicles) or is part of the coil pack setup on newer ones. It physically rotates, contacting the terminals that lead to each spark plug. It’s a pretty simple part mechanically, but vital. If the rotor fails, you won't get a spark in one or more cylinders. You’ll notice if that happens – really rough running, misfires, poor fuel economy, and potentially it won’t even start. It acts like a shield, protecting the ignition system from some of the high voltages involved. Over time, they can crack or corrode from the heat and electricity, leading to those problems. A bad rotor can also cause a noticeable hesitation when accelerating. You can find replacements pretty easily, even online at places like Fixparts Online if you’re comfortable doing the job yourself. It’s a fairly inexpensive part to replace and can make a big difference in how your engine runs. Get more value: Rotor (MPN 079905234B) is protected by a 12-month warranty!
