Keep spark reaching each cylinder in firing order with the Standard Ignition Distributor Rotor JR-100. It is a direct-fit replacement for many vehicles, among them the 1994-1996 Honda Passport, 1991-1997 Isuzu Rodeo and 1989-1994 Isuzu Amigo. See the "Vehicles it fits" section for the full list and engine details.
The rotor turns with the distributor shaft and routes high-voltage current from the ignition coil to each distributor cap terminal in turn, so spark arrives at the correct cylinder.
- High dielectric-strength engineering polymer: designed to resist electrical breakdown and arcing and support a long service life.
- Noise-suppressing coating on the segment: helps prevent electrical interference with the radio and other electronic circuits.
- Solid brass segment: built to resist pitting and erosion for extended life.
- Shaft mounting bushing: provides a proper fit on the distributor shaft.
Signs a distributor rotor may need replacing include engine misfires, hard starting, rough running, or a burned, pitted, or cracked rotor tip found on inspection. If a worn rotor is the cause, the JR-100 replaces it. Diagnose the ignition system before replacing parts.
