The distributor cap & rotor are just two pieces of this type of ignition system which is typically driven by the engine’s camshaft. The distributor is the device that delivers the ignition spark to the spark plugs at a precise time, and spark timing is critical. Any wear or component out of place in this type of system will result in failure. Within the distributor and mounted to it are many individual pieces which allow the distributor and system to be maintained and repaired to keep it in top working order.

Product Features:

All products are constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
Cap terminal conductor wires formed with precision guided machines to ensure precise final location in the final housing assembly.
Terminal inserts manufactured to precise tolerances to ensure a guaranteed electrical connection between the cap conductor wires and spark plug wire terminals.
Distributor rotor blade coated with RFI coating to prevent electrical magnetic interference with the vehicles electrical system.
