Motorcraft DG-542 Ignition Coil 8-Pack — Complete Solution for Ford F-150 and Mustang 5.0L Coyote V8 Ignition Problems
If you are experiencing ignition failure codes and erratic operation in your 2011-2015 Ford F-150 or Mustang GT 5.0L Coyote V8, the Motorcraft DG-542 ignition coil is the OEM solution. In this guide, we'll explain what the DG-542 does, why replacing all 8 is the right decision, and how to do it yourself.
What is the Motorcraft DG-542?
The DG-542 is an ignition coil that fits onto the Original Motorcraft spark plug for the 2011-2015 Ford F-150 and Mustang GT 5.0L Coyote V8. Each spark plug has a coil directly attached to it (a total of 8 coils for the V8), and these coils produce a high-voltage spark each time that cylinder fires. When a DG-542 fails, that cylinder immediately gives an ignition fault, and you will see P0301–P0308 codes, erratic idling, and loss of power.
Symptoms of a faulty DG-542:
Engine malfunction light illuminated with P0300–P0308 ignition fault codes
Erroneous idling or engine shaking while stationary
Hesitation or wobbling during acceleration
Loss of power, particularly noticeable in the 5.0L Coyote
Poor fuel economy
Difficulty starting in cold weather
Why should you replace all 8 DG-542 coils at once?
All 8 coils are the same age and have the same mileage; if one fails, the others will soon fail as well.
A single faulty coil puts extra strain on the remaining 7 coils, accelerating their failure.
Replacing all 8 coils at once saves on repeated labor for future ignition problems. It ensures balanced ignition performance in every cylinder of your Coyote V8 engine. Key Features

How to Replace All 8 DG-542 Coils — Step-by-Step
Before you begin, disconnect the negative terminal of the battery.
Remove the engine cover, if applicable.
Use compressed air to clean any debris around each coil before removing it.
Remove the electrical connector — press down on the locking tab and pull up simultaneously.
Remove the coil retaining bolt and pull the old coil straight up from the plug.
Press the new DG-542 coil firmly onto the spark plug until it clicks into place.
Reinstall the bolt and reconnect the electrical connector.
Repeat for all 8 cylinders.
Reconnect the battery, clear any ignition fault codes, and take a test drive.
Note: On the F-150, the rear cylinders are located close to the engine bay — use an extension and swivel link to facilitate access.
💡 Pro tip: For a complete Coyote V8 service, replace your SP-548 spark plugs along with your DG-542 coils. If your ignition coils need replacing and your spark plugs have the same mileage, perform both operations at once.
