Your spark plugs are there to ignite the fuel and air mixture inside your combustion cylinders. The spark is created through electricity that travels through your BMW 318i spark plug wires from your distributor rotor. Since your 318i spark plug wires handle tens of thousands of volts at a time, they have to be pretty tough.

The silicon jacket covering your spark plug wires is made for durability, because even the smallest crack can allow the electricity conveyed by the wires to escape. Faulty BMW 318i spark plug wires can cause rough engine performance, misfires, and ruined spark plugs. Over time, despite their heavy-duty construction, your 318i spark plug wires are going to become worn.

You may not be able to detect cracks or damage to your spark plug wires just by looking at them, as there may be cracks in the jacket interior or the wires themselves may be damaged. It is a good idea to change your BMW 318i spark plug wires with every engine tune-up, and also whenever you replace your spark plugs. It is important to realize that your 318i spark plug wires are different lengths, because your spark plugs are found at various points in your engine.
