Spark plug leads, also known as spark plug wires, are essential components of an internal combustion engine. They are responsible for delivering high-voltage current from the ignition coil to the spark plugs, which then ignite the air-fuel mixture in the engine’s cylinders. Faulty spark plug leads can lead to a variety of engine problems, including misfires, reduced power, and increased fuel consumption.
Checking spark plug leads is a relatively simple and inexpensive procedure that can help to prevent these problems. It is important to check the leads regularly, especially if you are experiencing any engine problems. The process of checking spark plug leads involves inspecting the wires for any damage, such as cuts, cracks, or fraying. You should also check the connections at each end of the wires to make sure that they are tight and secure.
