<h2>What does an ignition coil do?</h2>
An ignition coil is one of the most important parts of the ignition system and has a lot of responsibility. The role of the ignition coil is to transform the 12 volts of battery power into high voltage to produce a spark in the <a href="https://a-premium.com/spark-plug">spark plug</a>. This generated spark then kindles the mixture of fuel and air in the engine cylinder, and the car is able to run and take you places.&nbsp;&nbsp; In the modern day, cars have a single coil for each cylinder. The ignition coil is usually fitted right above the spark plug. This position of the ignition coil is called a coil-on-plug setup. As the ignition coil is a major part of the engine, it should be taken care of. If the ignition coil fails at some point, your engine will not perform at all. Damaged and faulty ignition coils can be a reason for a significant safety threat. Furthermore, if you don't take care of the ignition coil, it could lead to costly repairs.
<h2>How to tell if an ignition coil is bad?</h2>
