This little guy basically distributes high voltage to the correct spark plug at the right time. Think of it like a traffic controller for electricity, making sure each cylinder gets the spark it needs to fire. It's a rotating arm with a conductive tip, and that tip sweeps past the distributor cap contacts. It’s part of your ignition system, specifically working with the distributor. The distributor itself gets power from the ignition coil, and the rotor is the final link in getting that high voltage to the spark plugs. It’s a pretty simple part, mechanically, but it’s crucial. Older vehicles, especially those with carburetors, really rely on a good rotor to run right. If it’s failing, you’ll notice if your engine is misfiring, struggling to start, or just running rough. It can also cause a loss of power, especially during acceleration. Because it rotates at engine speed, it’s subject to wear and tear. The carbon contact on the tip can erode over time, or the rotor itself can crack. Replacing it is often a relatively inexpensive way to get your engine running smoothly again. You can find these pretty easily; we stock a lot of them, or places like Fixparts Online have a good selection if you prefer to order that way. It’s one of those parts that's small, but acts like a shield protecting the overall performance of your engine. What sets us apart: Ignition Rotor (MPN 12111707263) includes a 12-month warranty!
