Distributor cap and rotor kits are essential components of the ignition system in most gasoline-powered vehicles. The distributor cap is responsible for distributing the high voltage from the ignition coil to the spark plugs in the correct firing order, while the rotor spins inside the cap and makes contact with each spark plug wire. Over time, these components can wear down and cause misfires or other ignition problems. A distributor cap and rotor kit is an easy and affordable way to replace these parts and ensure reliable ignition performance. They come in a variety of sizes and configurations to fit most vehicles, and are often sold as a set to ensure compatibility.
