Help keep high-voltage spark reaching each cylinder in firing order with the Standard Ignition Distributor Rotor GB-351. It is a direct-fit replacement for several vehicles, among them the 1990-1991 Rolls-Royce Corniche II, the 1990-1991 Rolls-Royce Silver Spirit, and the 1990-1991 Rolls-Royce Silver Spur. See the "Vehicles it fits" section for the full list and engine details.
The rotor turns with the distributor shaft beneath the cap. It carries ignition-coil voltage from the center terminal across to each spark plug terminal in turn. Standard Ignition is a global manufacturer of original equipment ignition products. It maintains complete quality control throughout manufacturing, from componentry to the finished product.
- High-grade dielectric-strength alkyd: Resists dirt sticking to the surface. This reduces carbon tracking and is intended to extend service life.
- Solid brass segments: Designed for better conductivity and higher-voltage spark delivered to the plugs.
- Shaft retention clips where required: Standard Ignition uses retention clips on its rotors where the application calls for them, for proper fit and performance.
- Decades of development: Draws on decades of Standard Ignition research and development in distributor caps and rotors.
Signs a distributor rotor may need replacing include misfires, hard starting, rough running, and a rotor that looks burned, eroded, or cracked or shows carbon tracking. These symptoms can have other causes, so diagnose the ignition system before replacing parts. The rotor is often serviced together with the distributor cap.

Frequently Asked Questions
What does the Standard Ignition GB-351 distributor rotor do?
It spins with the distributor shaft under the cap. It transfers ignition-coil voltage from the center terminal to each spark plug terminal in firing order.
Which vehicles does the GB-351 fit?
It is listed for several vehicles, including the 1990-1991 Rolls-Royce Corniche II, 1990-1991 Rolls-Royce Silver Spirit, and 1990-1991 Rolls-Royce Silver Spur. See the "Vehicles it fits" section for the full list.
Why does this rotor use brass segments?
Standard Ignition uses solid brass segments on its distributor rotors for better conductivity and higher-voltage spark to the plugs.
What are signs the distributor rotor may need replacing?
Signs include misfires, hard starting, rough running, and a burned, eroded, cracked, or carbon-tracked rotor. These signs can have other causes, so diagnose the ignition system first.
What part numbers does the GB-351 interchange with?
It cross-references 12-0151 (120151), D633, 04155, 1234332333, RB979, EP731, 19017234, 94460290100, 94460290600, and 94460290601.
