Standard Ignition Distributor Cap P/N:LU-433
$32.99

Keep high-voltage spark reaching every cylinder in the correct firing order with the Standard Ignition Distributor Cap LU-433. It's a direct-fit replacement for a broad list of British and European V8s, including the 1970-1971 Aston Martin DBS (V8-5.3L), 1969-1970 Bentley T1 Series (V8-6.2L), 1994-1995 Land Rover Discovery (V8-3.9L), 1987-1989 Rolls-Royce Silver Spirit (V8-6.8L), and 1970-1973 Triumph Stag (V8-3.0L) — see the Buyer's Guide tab for all 26 applications.

A distributor cap routes voltage from the ignition coil to each spark plug wire as the rotor sweeps beneath its terminals. A cracked, carbon-tracked, or corroded cap can be a source of misfires, hard starting, and rough running.

  • High dielectric strength: glass/mineral reinforced polyester resin for less carbon tracking and greater resistance to electrical breakdown.
  • 9 terminals: with a clip-style mount and vertical tower position.
  • Aluminum contact terminals: for solid electrical connections.
  • Black cap, sold on its own: the ignition rotor, spark plug wires, gaskets, and screws are not included.

If a failed distributor cap is the cause of your ignition trouble, this replaces it. Country of origin: Italy.

Frequently Asked Questions

What does the LU-433 distributor cap do?

It routes high-voltage current from the ignition coil to each spark plug wire in firing order as the rotor turns beneath its terminals, so every cylinder fires at the right time.

Does it include a rotor, plug wires, or screws?

No. This listing is for the distributor cap only — the ignition rotor, spark plug wires, gaskets, and mounting screws are not included.

What vehicles does it fit?

It's a direct-fit replacement across 26 British and European V8 applications from Aston Martin, Bentley, Land Rover, Rolls-Royce, Rover, and Triumph. See the Buyer's Guide tab for the full year-by-year list.

What are signs the cap may need replacing?

Cracks, carbon tracking, or corroded terminals can lead to misfires, hard starting, or rough running. Diagnose the cause first, since these symptoms can have other sources.

How many terminals does it have and how does it mount?

It has 9 terminals with aluminum contacts, a clip-style mount, and a vertical tower position, finished in black.
