Basically, the distributor cap takes the high voltage from your ignition coil and distributes it to the correct spark plug, at precisely the right time. Think of it like a traffic controller for electricity – making sure each cylinder gets its spark when it needs it to fire. It has terminals inside that connect to the spark plug wires, and a rotor that spins around inside, sending that voltage where it needs to go. It’s a key part of your ignition system. The engine needs that spark to burn the fuel – air mixture, and the distributor cap is what makes that happen consistently. It’s connected directly to the distributor itself, which is timed to the engine’s rotation. So, everything has to be pretty precise. You’ll notice if this cap starts to fail because the engine timing gets off. This cap acts like a shield against high voltage, but over time, heat and moisture can get to it. It can crack, corrode, or develop carbon tracking inside. When that happens, the spark jumps to the wrong place, or doesn’t happen at all. This causes misfires, rough idling, loss of power, and decreased fuel economy. It’s one of those things that, when it goes bad, will really make itself known. Luckily, they’re fairly inexpensive to replace, and a pretty straightforward job for a lot of people. We carry a good selection here, and Fixparts Online is always a good resource if you prefer to order online. It's a relatively easy part to tackle yourself, and getting a new one can really bring your engine back to life.
