Help deliver high-voltage spark to each plug in the correct firing order with the Standard Ignition Distributor Rotor JR-105. It fits many Nissan vehicles, among them the 1986-1995 Nissan Sentra, 1993-1996 Nissan Tsuru and 1993-1996 Nissan Pickup. See the "Vehicles it fits" section for the full list and engine-specific details.
The rotor turns with the distributor shaft. It carries current from the cap's center terminal to each outer terminal in sequence, so every plug fires in turn.
- Quality control: Standard Ignition is a global manufacturer of original equipment ignition products. It controls quality through every stage of production, from components to the finished product.
- Dielectric alkyd: The high-grade, dielectric-strength alkyd resists dirt sticking to it. This is designed to reduce carbon tracking and extend service life.
- Solid brass segments: The brass segments are designed for better conductivity and higher-voltage spark to the plugs.
- Shaft retention clips: The rotor uses retention clips where the application requires them, for a secure fit on the shaft.
Signs a rotor may need replacing: misfires, hard starting, rough running, or a no-start. On inspection, look for a burned contact tip, cracks, or carbon tracks. If a worn rotor is the cause, this unit replaces it. Diagnose the ignition system first, since other components can produce the same symptoms.

Frequently Asked Questions
What does a distributor rotor do?
It turns with the distributor shaft and passes high-voltage current from the cap's center terminal to each outer terminal in firing order. This sends spark to the correct plug.
Which vehicles does the JR-105 fit?
It is listed for many Nissan vehicles, including the 1986-1995 Nissan Sentra, 1993-1996 Nissan Tsuru and 1993-1996 Nissan Pickup. See the "Vehicles it fits" section for the full list and engine details.
What are the rotor's contact segments made of?
Standard Ignition specifies solid brass segments. They are designed for better conductivity and higher-voltage spark to the plugs.
How does this rotor address carbon tracking?
It uses a high-grade, dielectric-strength alkyd that resists dirt sticking to it. This is intended to reduce carbon tracking and extend service life.
What are signs a distributor rotor may need replacing?
Possible signs include misfires, hard starting, rough running or a no-start, plus a burned tip, cracks or carbon tracks. Diagnose first, since other ignition parts can cause the same symptoms.
