Ignition Coil Cap

An ignition coil cap, also known as a spark plug cap or spark plug boot, is a protective cover that is placed over the top of the ignition coil. It is typically made of rubber or silicone material and serves as a barrier between the ignition coil and the spark plug wire.

The ignition coil cap plays a crucial role in the ignition system of a vehicle. It helps to prevent moisture, dirt, and other contaminants from entering the ignition coil and causing damage. It also helps to maintain a secure connection between the ignition coil and the spark plug wire, ensuring that the electrical current is properly transmitted.

In addition to protecting the ignition coil, the cap also helps to suppress electromagnetic interference (EMI) that can be generated by the ignition system. This interference can disrupt the operation of other electronic components in the vehicle, so the ignition coil cap helps to minimize this interference and maintain the proper functioning of the vehicle's electrical system.

Overall, the ignition coil cap is an important component of the ignition system, providing protection and ensuring the efficient operation of the vehicle's engine.
