Technically, an ignition coil in a vehicle is also known as the spark coil. It is an induction coil that is found in the vehicle’s ignition system. It works to transform a storage battery’s 12 volts to the thousands of volts needed to trigger the spark plugs of the auto. It is a form of autotransformer together with a contact breaker that does the actual conversion of the low voltage to a much higher voltage requirement for the spark plugs in an internal combustion engine.

The ignition coil connects the high voltage terminal to the tip of the spark plug. This high voltage terminal is at the top center of the coil which has a deep socket and consists of a cable wire that is used in a power cord for a good insulation. It is always best to keep the wires a few centimeters apart and safe from moisture as the high voltage can cause defects in the insulation of the ignition coil. Some ignition coils in electronic ignition systems are technically located inside the distributor cap.

The distributor has less ignition system where the coils directly fire the spark plugs. The number of ignition coil varies with the system. Some have one ignition coil for every two cylinders while others have one ignition coil for each cylinder. If your auto’s engine bucks, runs rough, surges, stalls, has decreased or poor fuel economy, and fails in the emission test, then it might have a problem in the ignition system or only in the ignition coil of your vehicle. The Hypertech Ignition Coil can cure these ignition problems in your auto as it will provide much more power and gives better fuel mileage. This product is guaranteed to be one of the best choices for your vehicle’s ignition coil replacements.
