Motorcraft ignition coils are made to the specifications of Ford vehicles. They are available in several types, depending on the make and model of the vehicle.
Coil on Plug Ignition System
The coil-on-plug (COP) system has one ignition coil for each cylinder. The ignition coil is directly mounted on top of the spark plug. This allows for a stronger and more precise spark. The COP ignition system is very reliable and requires little maintenance.
Wound Ignition Coil
This is the traditional Motorcraft ignition coil. It has two sets of wire windings around a magnetic iron core. One set of windings is called the primary, and the other is called the secondary. The primary has fewer loops than the secondary. When the current from the battery flows into the primary winding, it creates a magnetic field. This magnetic field is the basis of the secondary winding. The coils work together like a transformer to boost the voltage. The Wound ignition coil is very affordable and easy to maintain.
Distributerless Ignition System (DIS)
In the distributor-less ignition system (DIS), the ignition timing is controlled electronically. This system has fewer moving parts and is more reliable. The DIS can improve engine performance and increase fuel efficiency. The Motorcraft ignition coil is compatible with both the coil-on-plug and coil-near-plug systems.
Coil Near Plug Ignition System
In the coil near plug ignition system, the ignition coil is located close to the spark plug but not directly on it. The coil is connected to the spark plug by a short high-voltage wire. This arrangement allows for a good spark, but it is not as effective as the coil-on-plug system.
Below are some of the specifications of Motorcraft ignition coils for Ford that retailers should take note of.
Compatibility
Motorcraft coils are designed for Ford vehicles. Retailers should ensure the coils are verified by Motorcraft to work with a specific make, model, and year of the car. This ensures they fit correctly and work optimally.
Primary and secondary windings
The motorcraft ignition coil has primary and secondary windings. The primary winding has 150 to 200 turns of thick wire, while the secondary has 1000 to 6000 turns of thinner wire. Together, they generate the high voltage needed to spark the fuel and air mix in the engine's cylinders.
Coil configuration
Motorcraft coils come in different configurations, such as single coil, coil pack, or coil-on-plug. Each has a specific number of terminals for connection to the battery and spark plugs. For example, coils-on-plug have one coil for each cylinder and require one coil and plug cable per cylinder. V8 and other larger engines need more coils than smaller 4-cylinder engines.
Voltage output
The ignition coil produces between 20,000 and 45,000 volts of spark energy, depending on the vehicle's engine type and requirements. Higher-performance vehicles need coils with more voltage output to ensure a strong spark even at high speeds. Retailers should match the voltage to what the vehicle's service manual specifies.
Resistance
Motorcraft coils have low, high, or dual-resistance ratings. Low-resistance coils provide a high-current spark but can quickly drain the battery. High-resistance coils give a weaker spark but last longer because they pull less from the battery. Dual coils switch between low and high resistance, depending on what the engine needs at the time. The resistance rating affects how well the spark plugs fire. Motorcraft coils are available in all three types with varying specifications.
Coil housing
Coil-on-plug and other ignition coils have durable plastic or metal housings. These protect the delicate internal parts from moisture, dirt, and damage. The materials used need to withstand the hot engine environment. Metal and high-temperature plastics last longer.
Integrated features
Some Motorcraft ignition coils have extra capabilities. For example, coils with built-in sensors monitor their own health in real-time. They can alert if a coil starts to fail. Coils with smart technology can adjust spark strength automatically based on driving conditions. These advanced features improve performance but also increase the cost.
Motorcraft ignition coils require minimal maintenance. However, there are a few things users can do to keep them in good condition. These include:
Consider the Make and Model
When selecting the proper Motorcraft ignition coils for a specific vehicle, the make and model are considered. Different vehicles have different coil requirements according to their engine configurations. For instance, a V6 engine will require more coils than a four-cylinder engine.
Check the Part Number
Every Motorcraft ignition coil has a unique part number. This number should be cross-referenced with the vehicle's manual or online Motorcraft coil catalog. This ensures that the exact match for the coil requirements is found.
Inspect the Old Coil
The old ignition coil should be inspected before purchasing a new one. This can give information about the coils previously used. Visible damages like rust, cracks, or wear should be noted. The type and specifications of the old coil can then be matched to a new Motorcraft coil.
Consult a Professional
When in doubt about which coil to choose, a professional mechanic can be consulted. Mechanics have experience working with different coils and can recommend the best based on the vehicle's performance history.
Read Reviews
Online reviews and testimonials from other users can be read. This gives insight into the reliability and performance of various Motorcraft ignition coils. Coils with higher ratings and praise for smooth operation should be selected.
Evaluate Cost
A budget needs to be set aside for purchasing Motorcraft ignition coils. While cheaper options are available, the overall value should be considered. Sometimes, spending a little more on a high-quality coil pays off in the long run through better vehicle performance and longevity.
Replacing Motorcraft coils is a straightforward DIY task. Here is a step-by-step guide on how to replace Motorcraft coils:

Step-by-step guide:
Q1: How long do ignition coils last?
A1: Ignition coils have no set time to last, but they are durable. They can last up to 100,000 miles or more. Several factors can affect the lifespan of ignition coils. For example, poor maintenance of the vehicle can lead to a shorter lifespan of the Motorcraft ignition coil.
Q2: What are the symptoms of a failing ignition coil?
A2: When the ignition coil is faulty, it will not supply the spark plugs with enough power. As a result, the engine will have a hard time starting. Other symptoms include a rough idling engine, misfires, and decreased engine power.
Q3: Can an ignition coil be replaced in isolation?
A3: Yes, an ignition coil can be replaced in isolation. However, it is advisable to replace all the coils. This is because the other coils will be worn out, and soon they will cause the same problem. Replacing all the coils will save time and money in the long run.
