What It Is Used For

• Restoring spark distribution in distributor-equipped ignition systems
• Replacing a worn, cracked, or carbon-tracked rotor
• Correcting misfire caused by poor rotor contact or indexing issues
• Addressing hard-start or rough-running conditions tied to ignition wear
• Supporting service on Ford, Lincoln, and Mercury distributor applications

Installation Notes and Tips

Verify distributor style before ordering, since fitment depends on details such as Triangular Rotor, EEC III, EEC IV, cap adapter, and module location. Match the vehicle year, make, model, and emissions or ignition-system notes exactly to the application listed for FD-117. Inspect the distributor cap, terminals, and ignition components during service to confirm proper rotor engagement.
