Route high-voltage spark from the rotor to each plug wire with the Standard Ignition Distributor Cap AL-493. It is a direct-fit replacement for the listed applications, including the 1939-1942 and 1946-1948 Chrysler New Yorker, 1948-1952 Hudson Commodore Series, 1949 Lincoln Cosmopolitan and 1951-1952 Packard Patrician, along with other Chrysler, Hudson, Lincoln and Packard models. See the Buyer's Guide tab for the full list and engine details.
Standard Ignition is a global manufacturer of original equipment ignition products. It keeps quality control in-house from individual components through to the finished cap.
- Cap material: Made from high dielectric strength, glass/mineral reinforced polyester resin. It is designed for less carbon tracking and greater resistance to electrical breakdown.
- RFI resistors: Fitted where specified to help suppress radio static.
- Terminals: Solid brass terminals, where available, give better connections and greater resistance to electrical pitting and corrosion.
- Development: Built on decades of Standard Ignition research and development in distributor caps and rotors.
The distributor cap works with the rotor to deliver ignition voltage to the correct spark plug wire. Signs a cap may need replacing include cracks, carbon tracks inside the cap, burned or corroded terminals, misfires, hard starting and rough running. Because the cap and rotor work together, inspect the rotor at the same time.
