Keep high-voltage spark reaching every plug in firing order with the Standard Ignition Distributor Rotor GB-329. It is a direct-fit replacement for many vehicles, among them the 1977-1979 Ford Pinto and 1977-1979 Mercury Bobcat. See the Buyer's Guide tab for the full list of applications and engine details.
The rotor turns with the distributor shaft and carries voltage from the coil terminal in the cap to each spark plug terminal in turn. Standard Ignition is a global maker of original equipment ignition products and maintains quality control through the whole manufacturing process, from component parts to the finished product. Its distributor caps and rotors draw on decades of research and development.
- Dielectric strength alkyd: the high-grade alkyd resists dirt build-up, which cuts carbon tracking for a longer service life.
- Solid brass segments: designed for better conductivity and a higher-voltage spark to the plugs.
- Shaft retention clips: used on applications that call for them, for proper fit and performance.
Signs a rotor may need replacing include misfires, hard starting, rough running, or a burned, cracked or carbon-tracked tip. Other ignition parts can cause the same symptoms, so diagnose the cause before replacing.
