OEM Mopar Distributor Caps

A distributor sends current from your vehicle's ignition coils to its spark plugs in the right firing order and at the right intervals. Its distributor cap, however, is a cover that protects the parts of a distributor and maintains contact between the distributor's internal rotor and the wires of a spark plug. Unfortunately, no distributor lasts forever. Luckily, the signs your distributor rotor and cap are worn out or damaged are easy to spot. They include cracks in the housing, a broken wire tower, and carbon tracks or burns on the distributor cap terminal.

What are the Symptoms of a Failing or Bad Distributor Rotor and Cap?

Keep an eye out for several. They include a lit Check Engine light, unusual engine noise, engine misfires, and a vehicle that just plain won't start. To catch them early, be sure to inspect both the rotor and distributor cap during routine tune-ups, about every 25,000 miles. When to replace them is straightforward: the recommendation is every 50,000 miles or so, at least. However, check your owner's manual to be sure. When it's time to buy new, be sure to get genuine Mopar distributor caps. They'll fit your factory distributor best. You can order one online from your OEM right here at our auto parts store.
