Distributor Caps

Definition of Distributor Caps as it relates to Automotive, Automotive Electrical, Timing Components

Distributor caps are essential components in an automotive electrical system, specifically within the timing components category. They serve as the housing for the distributor rotor, which directs the high voltage from the ignition coil to the spark plugs in the correct firing order. The cap itself is typically made of plastic or composite materials and features several terminals on its periphery that connect to the spark plug wires. Over time, these caps can wear out or become damaged, leading to misfiring or a no-start condition. Therefore, it's important to regularly inspect and replace distributor caps as needed to ensure optimal engine performance.
