Product Details and Specifications
The Standard Ignition UF-646 ignition coil features a coil-on-plug ignition type that mounts directly onto the spark plug, improving ignition efficiency and reducing energy loss. Its bolt-on mount type includes a mounting bracket for secure installation in the engine bay. The coil operates at 12 volts and uses a blade-type male terminal with three terminals for reliable electrical connections. The female connector is designed with a plug-in style and features rectangular and oval shapes to ensure proper fitment. This ignition coil is not oil-filled and does not include grease packs or additional hardware, so installation requires existing mounting hardware or compatible fasteners.

It is designed to replace faulty or worn ignition coils in these models, restoring proper ignition system function.
Common Issues Addressed by UF-646 Ignition Coil
- Engine misfires or rough idling caused by weak or failing ignition coils

Installation Notes and Tips
Installation of the Standard Ignition UF-646 ignition coil requires basic mechanical skills and tools. Since the coil mounts with bolts and includes a mounting bracket, ensure the engine is cool before beginning work. Disconnect the battery to prevent electrical shorts. Carefully unplug the female connector and remove the old coil before installing the new coil. Verify the connector shape and terminal alignment for a secure fit. No additional hardware or grease pack is included, so retain or source necessary mounting bolts. Follow vehicle-specific service manual instructions for torque specifications and safety precautions.
