Detailed Description

FD-312 is a replacement distributor rotor used in ignition systems where the rotor transfers spark from the distributor cap to the correct terminal. This part number covers a wide range of Ford truck and car applications, including 1984 Ford F-150 with round rotor and EEC IV, 1984 Ford F-250 and F-350 with screw-on rotor and EEC IV, and 1988-1996 Ford Bronco with screw-on rotor. It also fits select 1983-1989 E-Series vans, 1983-1985 Ranger, 1984 Mustang, and several Lincoln and Mercury models listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Engine misfire caused by worn rotor contacts
• Hard starting related to weak or inconsistent spark transfer
• Rough idle from ignition timing or spark distribution issues
• Intermittent spark loss inside the distributor
• Ignition service needs on Ford Bronco, F-150, E-Series, and related applications

Installation Notes and Tips

Verify distributor style before ordering, since fitment varies by screw-on rotor, bolt-on rotor, round rotor, and cap adapter configurations. Match the vehicle year, make, model, and listed notes exactly to the application. Inspect the distributor cap, ignition wires, and related ignition components during service to confirm proper spark delivery after installation.

Quality Assurance

Standard Ignition FD-312 is cataloged as Blue Streak Premium Quality for the listed applications and is backed by Standard Ignition’s product engineering and application-specific fitment data.
