Motorcraft DG-513 Ignition Coil 6-Pack — The Complete Fix for Ford 3.0L V6 Misfires
If your Ford Escape, Taurus, Five Hundred, or Freestyle is throwing misfire codes and running rough, the Motorcraft DG-513 ignition coil is almost certainly the culprit. The 3.0L DOHC V6 is one of Ford's most widely used engines — and when the ignition coils start to go, replacing the complete set of 6 at once is the smartest move you can make. Here's why, and how to do it yourself.
What is the Motorcraft DG-513?
The DG-513 is a Genuine Motorcraft coil-on-plug ignition coil for Ford's 3.0L DOHC V6 Duratec engine. It sits directly on top of each spark plug — one coil per cylinder, six total for the V6 — and delivers a high-voltage spark every time that cylinder needs to fire. When a DG-513 fails, the affected cylinder misfires and you'll immediately notice rough running, hesitation, and a check engine light.
Symptoms of a failing DG-513 ignition coil
Check engine light with misfire codes P0300–P0306
Rough idle or engine shaking — especially noticeable at a stop
Hesitation or stumbling during acceleration
Poor fuel economy
Engine misfires under load
Hard starting in cold weather
The misfire code tells you exactly which cylinder has failed — P0301 is cylinder 1, P0302 is cylinder 2, and so on. But even if only one coil has triggered a code, read on to understand why replacing all 6 at once is the right call.
Why replace all 6 DG-513 coils at once?
This is the most important question Escape, Taurus, and Freestyle owners ask when they get a misfire code. Here's the honest answer:
All 6 coils have the same age and mileage — if one has failed, the others are under the same stress and close behind
A single failed coil puts extra ignition load on the remaining 5, accelerating their failure
Replacing one coil now and coming back 5 more times individually costs far more in total time and labor
Replacing all 6 at once guarantees balanced ignition performance across every cylinder
You save $216 vs buying 6 singles at AutoZone ($135 each)
Experienced Ford mechanics and dealership technicians almost always recommend the full 6-coil replacement on high-mileage 3.0L V6 engines. It's one of those jobs where doing it right once saves you money and headaches for years.

How to replace all 6 DG-513 coils — step by step
Disconnect the negative battery terminal before starting
Remove the engine cover if present
Working one cylinder at a time, unplug the electrical connector from the coil
Remove the coil retaining bolt
Pull the old coil straight up off the spark plug
Push the new DG-513 firmly down onto the spark plug until it seats fully
Reinstall the bolt and reconnect the electrical connector
Repeat for all 6 cylinders
Reconnect the battery, clear any misfire codes, and test drive
