Standard Motor Products
Help keep high-voltage spark arriving at each cylinder in turn with the Standard Ignition Distributor Rotor JR-75. It is a direct-fit replacement for many vehicles, including the 1971-1979 Toyota Celica, 1976-1987 Subaru DL and 1985-1989 Suzuki Samurai. See the "Vehicles it fits" section for the full list of applications.
The rotor mounts on the distributor shaft and turns with it. It carries current from the ignition coil to each terminal inside the distributor cap in firing order. Signs the rotor may need replacing include misfires, hard starting, rough running, or a tip that looks burned, pitted or carbon-tracked. Other ignition components can cause the same symptoms, so diagnose the cause first. If a worn rotor is the cause, the JR-75 replaces it.
