Distributor caps are subject to wear from the electrical arcing between the rotor and cap contacts, as well as heat deterioration over time. Regular replacement as part of routine maintenance helps prevent engine misfires, hard starting, reduced performance, and poor fuel efficiency. Bosch recommends replacing the distributor cap along with the distributor rotor and spark plug wires during scheduled tune-ups.
