A spark plug suppressor is a device that is fitted to the spark plug wire in an internal combustion engine. The primary function of a spark plug suppressor is to reduce electromagnetic interference (EMI) caused by the engine's electrical system. EMI can interfere with other electronic equipment in the vicinity of the engine, such as radios and other communication devices. The suppressor is typically made of a metallic coating that helps to reduce the amount of EMI that is generated by the spark plug. This coating is usually made of a combination of metals such as nickel, iron, and copper, which are effective at absorbing electrical energy. The suppressor is designed to ensure that the engine runs smoothly and without interference to other electronic equipment in the vicinity.

Installing a spark plug suppressor can provide numerous benefits, such as reducing the amount of static and radio interference in your vehicle. Additionally, it can help to prevent damage to electronic equipment, which can be caused by high levels of electromagnetic interference. The suppressor works by dampening the electrical pulses that are generated by the spark plug. By absorbing these pulses, the suppressor prevents them from affecting other electronic equipment in the vicinity. This helps to ensure that all electronic equipment in the car functions properly and that you get the best possible performance from your vehicle. The suppressor ensures that the energy generated by the spark plug is used efficiently and safely, without any unnecessary interference to other systems in the car.
