Standard Ignition Distributor Cap P/N:LU-437
Standard Motor Products
Keep spark firing crisply to every cylinder with the Standard Ignition Distributor Cap LU-431, the component that routes high-voltage from the coil through the rotor and out to each spark plug wire. It fits the 1972-1987 Jaguar XJ6 and the 1982-1984 Jaguar Vanden Plas — see the "Vehicles it fits" section for engine-level details.
Cracks, carbon tracking, or corroded terminals in a distributor cap can cause misfires, rough running, and hard starting; if a worn cap is the cause, this replaces it. Diagnose the cause before replacing.

This part cross-references / interchanges with the following part numbers:
What does a distributor cap do?
It routes high-voltage from the ignition coil through the rotor and out to each spark plug wire in the firing order, so every cylinder receives spark.
Which vehicles does the LU-431 fit?
It fits the 1972-1987 Jaguar XJ6 and the 1982-1984 Jaguar Vanden Plas. Check the "Vehicles it fits" section to confirm the fit for your vehicle.
What are signs my distributor cap may need replacing?
Cracks, carbon tracking, or corroded terminals can lead to misfires, rough running, and hard starting. Diagnose the cause before replacing.
What is the cap made of?
It is molded from high dielectric strength, glass/mineral reinforced polyester resin for less carbon tracking and greater resistance to electrical breakdown.
Does it have RFI resistors and brass terminals?
RFI resistors are included where specified to reduce radio static and voltage spikes, and solid brass terminals are used where available for better, corrosion-resistant connections.
