Standard Ignition Distributor Cap P/N:LU-439
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.
If a failed distributor cap is the cause of your ignition trouble, this replaces it. Country of origin: Italy.
