There are a lot of factors to consider when choosing an ignition coil for your car. In this post, we’ll compare the MSD Ignition Coil to the stock coil to help you decide which is best for you. Keep in mind that there are many other factors to consider besides just performance, so be sure to do your own research before making a purchase.

What Is MSD Ignition Coil?

MSD Ignition Coil is an electronic device that replaces the points and condenser in an ignition system of a gasoline engine. It produces a high-voltage spark that ignites the fuel/air mixture in the engine’s cylinders. The ignition coil is powered by the battery, and it sends sparks to the spark plugs at precisely the right time to ignite the fuel/air mixture.

E-core Winding

One of the features of MSD Ignition Coils is their e-core winding. This winding helps to keep the primary and secondary windings tightly together, eliminating any possibility of the windings unwinding or coming apart. This results in greater durability and longer life for the coil. Additionally, it ensures that the coil will fire consistently, regardless of how many times it’s been used.

Direct fit

The MSD Ignition Coil is a direct-fit coil that is designed for use with an MSD ignition system. This coil will provide you with the strong spark you need to ensure optimal performance from your engine. The MSD Ignition Coil features include high voltage output, quick rise time, and low primary resistance. These features combine to give you a reliable ignition system that will deliver consistent performance. Whether you are looking for an upgrade from your factory ignition system or want a reliable ignition system for your race car.

Sturdy Metal Housing

One of the features of the MSD Ignition Coil is that it has a sturdy metal housing. This housing helps to protect the ignition coil from damage, which can occur when the engine is running or when it’s being serviced. Additionally, this metal housing also helps to dissipate heat, which can cause problems with the ignition coil.

Potting Material Protects

The MSD ignition coil features potting material that helps protect the windings from moisture and contaminants. Additionally, this potting material also helps to provide thermal insulation, which prevents the coil from overheating.

What Is a Stock Coil?

A stock coil is a type of ignition coil that is commonly used in many vehicles. It is a simple coil that is made up of two wires wrapped around a metal core. The primary winding goes to the igniter, while the secondary winding goes to the spark plug. When the current from the igniter hits the spark plug, it causes a spark that ignites the fuel.


One common feature of stock ignition coils is the resistor. This resistor helps to limit the current flow through the coil, and it’s generally located in the primary winding. When it comes to upgrading your ignition coil, you’ll want to look for a model that doesn’t include this resistor. This will help improve spark energy and allow for more reliable combustion.

Primary and Secondary Winding

A stock ignition coil has two windings: the primary winding and the secondary winding. The primary winding is responsible for generating the initial spark, while the secondary winding creates a higher-voltage spark that’s strong enough to jump across the air gap and ignite the fuel mixture in the engine.

Special Crimped and Soldered Internal Connection

Stock ignition coils have a special crimped and soldered internal connection that helps to ensure reliable performance. The coil is also sealed in epoxy to protect it from the elements. This construction helps to ensure that the coil will provide consistent spark output for many years.

Highest Quality Copper

The stock ignition coil in your car is designed to provide the highest quality copper winding and insulation possible. This ensures that the spark plug gets the best possible discharge, resulting in more efficient combustion and better engine performance. While aftermarket ignition coils may be cheaper, they often don’t provide the same level of quality or reliability. So if you’re looking for the best possible performance from your vehicle, stick with a stock ignition coil.
