• Other Names:

  Coil Assembly Ignition, DG565

• Description:

  This is the Genuine Ford primary ignition coil for 18-25 F-150 and Mustang equipped with the 5.0L Coyote V8 engine. The coil is a coil-on-plug pencil-style unit that mounts directly to the spark plug and provides the high-voltage discharge required to fire the plug at the engineered timing and energy for this engine. Construction uses a Ford-spec primary winding, secondary, and silicone boot rated for the underhood temperature of the 5.0L valley. non-OEM cross-references include UF835 and DG565. A failed coil shows up as a single-cylinder misfire, a P0300-family code that points to a specific cylinder, rough idle, and a check engine light that can be cleared but returns under load. Replacement is appropriate after a confirmed coil failure or as preventive service at high mileage along with spark plugs. Install with the engine cool, on a clean valve cover, with the coil seated fully onto the spark plug terminal, the retention bolt torqued to the published value, and the harness connector clicked into the coil body. Clear stored codes and verify clean idle and a stable misfire counter across a full warm-up cycle.
