ACDelco Distributor Caps & Rotors

ACDelco Distributor Caps have metal inserts designed to provide the best possible fit for maximum conductivity between the distributor towers and spark plug wires. Markings or locator keys on ACDelco Caps are similar to OE parts for simple installation. Vent caps on select ACDelco Distributor Caps are also similar in design to OE. Full anti-arc barriers reduce the possibility of secondary voltage arcs that can cause engine misfiring.
