Route high-voltage spark from the rotor to each plug lead with the Standard Ignition Distributor Cap DR-405. It fits many vehicles, among them the 1959-1960 Jeep CJ5, 1959-1960 Jeep CJ6 and 1963-1975 Triumph Spitfire, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The distributor cap covers the distributor and carries ignition current from the spinning rotor to each spark plug wire terminal. Standard Ignition keeps quality control in place throughout manufacturing, from the individual components to the finished cap.
- Insulating cap body: made of high dielectric strength, glass/mineral reinforced polyester resin for less carbon tracking and greater resistance to electrical breakdown.
- RFI resistors (where specified): intended to help suppress radio static.
- Solid brass terminals (where available): designed for better connections and greater resistance to electrical pitting and corrosion.
- Research-backed design: developed from decades of Standard Ignition research and development on distributor caps and rotors.
Signs a distributor cap may need replacing include cracks, carbon tracks or corroded terminals inside the cap, misfires, hard starting and rough running. These symptoms can have other causes, so diagnose the ignition system before replacing parts.

Frequently Asked Questions
Is this the right distributor cap for a 1963-1975 Triumph Spitfire?
Yes. The DR-405 is listed as a direct-fit replacement for the 1963-1975 Triumph Spitfire. Check the "Vehicles it fits" section to confirm your vehicle.
Which Jeep models does the DR-405 fit?
It is listed for the 1959-1960 Jeep CJ5 and the 1959-1960 Jeep CJ6. The "Vehicles it fits" section shows every listed vehicle.
What does a distributor cap do?
It covers the distributor and carries high-voltage ignition current from the rotor to each spark plug wire terminal, so each plug receives its spark.
What is the DR-405 cap made of?
Standard Ignition makes its distributor caps from a high dielectric strength, glass/mineral reinforced polyester resin. The resin is designed for less carbon tracking and greater resistance to electrical breakdown.
What are signs my distributor cap may need replacing?
Look for cracks, carbon tracks or corroded terminals, along with misfires, hard starting or rough running. These can have other causes, so diagnose the ignition system first.
