Distributor Cap

Distributor caps, found within the ignition system of many gasoline engines, direct high-voltage electricity to the correct spark plug for combustion. Located atop the distributor, these caps house the rotor and terminals that distribute spark. A properly functioning distributor cap is crucial for consistent engine firing, optimal performance, and reduced emissions in vehicles utilizing a traditional distributor-based ignition system. These caps are constructed from durable materials to withstand high temperatures and electrical stress. Examples in our assortment include Bosch distributor caps (MPN 1235522413, 3397011549), and caps for commercial vehicles like the MAN MPN 81903106018 and Scania MPN 2753171.
