The cap of your distributor covers the moving parts inside and holds the contacts for the spark plug wires. If it’s damaged, you can lose spark energy and performance, so keep an eye on it during routine maintenance, and if you need a new distributor cap, you’ll find it at Summit Racing Equipment!

No matter what sort of distributor you’re using—points, magnetic, or optical—it will have a cap made of an insulating material. Most distributor caps have one terminal post per cylinder, to which the spark plug wire attaches. Many caps have these posts parallel to the distributor shaft, while others,...

Engine heat cycles and vibration can damage the insulating material of the distributor cap, which allows some of the spark energy to escape. This can lead to a weak spark and incomplete ignition, so be sure to inspect it for damage at every tune-up.

Summit Racing Equipment’s powerful Make/Model and Make/Engine search tools can help you find the distributor cap compatible with your vehicle. You can also search by distributor model or style.
