Send high-voltage spark to each cylinder in firing order with the Standard Ignition Distributor Rotor JR-166. It is a direct-fit replacement for many vehicles, among them the 1995-1997 Dodge Avenger, 1995-1997 Dodge Stratus and 1995-1997 Chrysler Cirrus. See the "Vehicles it fits" section for the full list and engine details.
The rotor turns with the distributor shaft under the cap. It passes the ignition coil's high voltage to each cap terminal in turn, and from there to the spark plug wires. The design draws on decades of Standard Ignition research and development.
- Controlled manufacturing: Standard Ignition is a global manufacturer of original equipment ignition products and keeps full quality control over production, from components to the finished product.
- High-grade dielectric alkyd: The high-grade dielectric strength alkyd resists dirt sticking, which helps reduce carbon tracking for extended service life.
- Solid brass segments: These segments provide better conductivity and help deliver higher-voltage spark to the plugs.
- Shaft retention clips where required: The rotor uses retention clips on applications that call for them, to help it fit properly.
Signs a distributor rotor may need replacing include engine misfire, hard starting, rough running, or a rotor tip that is burned, worn, or marked by carbon tracks. If a worn rotor is causing the problem, this part replaces it. Inspect the distributor cap during the same job.

Frequently Asked Questions
What does a distributor rotor do?
It turns with the distributor shaft and passes high voltage from the ignition coil to each distributor cap terminal in turn, sending spark to the plug wires in firing order.
Which vehicles does the Standard Ignition JR-166 fit?
It fits many vehicles, among them the 1995-1997 Dodge Avenger, 1995-1997 Dodge Stratus and 1995-1997 Chrysler Cirrus. See the "Vehicles it fits" section for the full list and engine details.
What are the rotor's segments made of?
The segments are solid brass. Standard Ignition uses them for better conductivity and higher-voltage spark to the plugs.
What are signs a distributor rotor may need replacing?
Signs can include misfire, hard starting, rough running, or a rotor tip that is burned, worn, or carbon-tracked. Diagnose the cause first, because other ignition parts can cause the same symptoms.
What part numbers does JR-166 interchange with?
It interchanges with D230, MD618663, CR929, RTRA32, MO33, and 19017209.
