2013 Ford Mustang - Distributor Cap

Ford Mustang Distributor Cap

The distributor cap on your Ford Mustang is the link between the distributor and the spark plugs and spark plug wires. On the underside of the cap are metal contact points, one for each spark plug wire. When the rotor touches the contact point, it sends energy from the ignition coil through the spark plug wire to the spark plug. Over time, the stress of the constant high voltage can cause the contacts to wear. The cap itself can also become brittle and crack. When the contacts are very worn, they could fail to contact the rotor, which can cause your Mustang not to start or lead to misfiring while the engine is running. Check the distributor cap, rotor, spark plugs and spark plugs wires for wear, and replace them if needed. Replacing these components is part of a regular tune-up, and can even increase gas mileage and performance. You can find all the ignition parts you need at O'Reilly Auto Parts to keep your Mustang running at its best.
