This little guy’s job is to distribute high voltage to the correct spark plugs, in the right firing order. It’s basically the final link in the ignition chain. The ignition coil sends a really powerful jolt of electricity, and the rotor spins around, directing that electricity to each spark plug so your engine can fire correctly. Think of it as a traffic controller for the electricity in your ignition system. The distributor cap covers it, and as the engine turns, the rotor’s tip brushes past the terminals inside the cap, sending that high voltage where it needs to go. It works closely with the ignition coil and distributor cap to get everything timed just right. If this thing goes bad, your engine won't run smoothly, if at all. You’ll notice if it’s failing—probably a rough idle, misfires, reduced power, and a check engine light. It’s a pretty crucial part, and a failing rotor can also cause a lot of stress on other ignition components. They don't last forever, so it’s good to be aware of it. You can find a replacement pretty easily, we even stock a good selection at Fixparts Online, and it’s one of those things that, while small, makes a big difference in how your car runs. It acts like a shield, protecting other more expensive parts by making sure everything fires when it should. Highly rated and reliable: Rotor (MPN 12111363334) includes a 12-month warranty!
