Distributor Caps

Distributor Caps are the ignition system parts that seal the top of a distributor and route high-voltage spark to each cylinder at the correct time. In this category you'll find premium replacement caps designed to cross-reference Lucas, Intermotor, Bosch, Marelli, Ducellier, TEC, and other OE numbers, making it easy to swap in a trusted, compatible part. Look for features like durable housing, tight insulation, moisture resistance, and reliable contact points that resist wear and arcing. Variations include Bosch-fit caps, Marelli Fiat caps, Lucas/Delco replacements, and weather-sealed designs for rough climates. Choose a cap that matches your distributor type and engine, ensuring proper fit, electrical conductivity, and long service life.
