Standard Ignition Distributor Cap P/N:LU-431
Keep spark jumping cleanly to every cylinder with the Standard Ignition Distributor Cap LU-420. The cap sits atop the distributor and routes high-voltage current from the rotor to each spark plug wire in the correct firing order. It's a direct-fit replacement for a long list of vintage imports and trucks, including the 1958-1969 Austin Healey Sprite, 1956-1962 MG MGA, 1962-1966 MG MGB, 1961-1964 Triumph TR4, 1963-1966 International Scout, and 1964-1973 Lotus Elan — see the Buyer's Guide tab for the full list of 43 applications.
Signs the original cap may need replacing include cracks, carbon tracking, corroded terminals, hard starting, or a rough-running misfire. If a failed distributor cap is the cause, this replaces it.

This part cross-references / interchanges with the following part numbers:
What does this distributor cap do?
It caps the distributor and routes high-voltage current from the rotor to each spark plug wire in the engine's firing order, so spark reaches every cylinder.
How do I know my distributor cap needs replacing?
Common signs include cracks, carbon tracking, corroded terminals, hard starting, or a rough-running misfire. Diagnose the cause first; if the cap is at fault, this replaces it.
What is the cap made of?
It's made of high dielectric strength, glass/mineral reinforced polyester resin for less carbon tracking, greater resistance to electrical breakdown, and superior performance.
Does it have RFI resistors and brass terminals?
RFI resistors are included where specified to help eliminate radio static and potential ECU-damaging spikes, and solid brass terminals are used where available for better, corrosion-resistant connections.
Will this fit my vehicle?
It fits 43 applications, including the Austin Healey Sprite, MG MGA/MGB, Triumph TR4, International Scout, and Lotus Elan. Check the Buyer's Guide tab to confirm your exact year, make, and model.
