Send coil voltage to each cylinder in firing order with the Standard Ignition Distributor Rotor JR-120. It fits many vehicles, among them the 1992-1995 Toyota 4Runner, 1992-1995 Toyota Pickup and 1993-1994 Toyota T100. See the Buyer's Guide tab for the full list and engine details.
The rotor mounts on the distributor shaft and spins inside the distributor cap. As it turns, it carries high voltage from the coil to each spark plug terminal in turn. Standard builds this rotor with the following features:
- Engineering polymer body: Made from a high dielectric-strength engineering polymer that is designed to resist electrical breakdown and arcing.
- Solid brass segment: The brass segment resists pitting and erosion.
- Noise-suppressing coating: A coating on the segment helps prevent electrical interference with the radio and other electronic circuits.
- Quality control: Standard is a global manufacturer of ignition products and maintains quality control throughout production, from componentry to the finished product.
Signs this part may need replacing: engine misfires, hard starting, rough running, or a rotor tip that looks burned, pitted, or cracked. Other problems can cause these symptoms too, so diagnose the ignition system before you replace parts. The rotor is commonly serviced together with the distributor cap.
