Keep spark voltage moving cleanly from the coil to every plug wire with the Standard Ignition Distributor Rotor JR-102. It is a direct-fit replacement for many vehicles, among them the 1985-1991 Toyota Corolla, 1986 Toyota Camry and 1985-1986 Toyota 4Runner.
Inside the distributor, the rotor turns with the distributor shaft. It passes high-voltage current from the center of the cap to each outer terminal in firing order. JR-102 includes these features:
- High dielectric-strength engineering polymer: designed to resist electrical breakdown and arcing for long life.
- Noise-suppressing coating: a coating on the segment is intended to keep electrical interference out of the radio and other electronic circuits.
- Solid brass segment: resists pitting and erosion for extended life.
- Shaft retention clips: help the rotor fit properly on the distributor shaft.
Signs a distributor rotor may need replacing include misfiring, hard starting, rough running, or a rotor tip that looks burned, eroded or cracked on inspection. If a worn rotor is the cause, JR-102 replaces it. Inspect the distributor cap at the same time.

Frequently Asked Questions
What does a distributor rotor do?
It turns with the distributor shaft and carries high-voltage spark from the center of the distributor cap to each outer terminal. Those terminals feed the plug wires in firing order.
Which vehicles does JR-102 fit?
It fits many vehicles, among them the 1985-1991 Toyota Corolla, 1986 Toyota Camry and 1985-1986 Toyota 4Runner. See the "Vehicles it fits" section for the full list and engine details.
What is the rotor's contact segment made of?
JR-102 uses a solid brass segment that resists pitting and erosion. The segment also has a noise-suppressing coating that helps prevent interference with the radio and other electronic circuits.
What are signs my distributor rotor may need replacing?
Possible signs include misfires, hard starting, rough running, or a burned, eroded or cracked rotor. These symptoms can have other causes, so diagnose the ignition system before replacing parts.
What part numbers does JR-102 interchange with?
It interchanges with numbers including 12-0215, 2-3840, D717, JA951, EP484, EP484SB, 94844585 and 1910216060. The full list appears on the Interchange line in the description.
