BMW 3-Series Spark Plug Wires, Ignition Wires

Also known as ‘ignition wires’ or ‘ignition cables’, the spark plug wires connect the distributor to the spark plugs of your BMW 3-Series. These wires carry high-voltage electricity required to generate a spark. In order to perform this function reliably and safely, the wires have a complex structure featuring several layers of isolation. And this isolation deteriorates over time causing leaks of electric power in various places of a cable. Sometimes, worn-out ignition wires can even show some kind of illumination if you open the hood at night while the engine is running. Also, the spark plug wires are continually exposed to heat and vibrations. Electrical leaks and wires' inner defects lead to ignition failures.

If there is something wrong with your ignition cables, both the performance and fuel efficiency of your vehicle go down markedly. Sometimes (but definitely not always), there is visible damage to the wires. Malfunctioning wires should be replaced as soon as possible; it is always reasonable to select heavy-duty ignition wires that come from reputable manufacturers. As our store cooperates with well-established aftermarket companies such as Standard, Bosch, Beck Arnley, Denso, and Beru, we offer you BMW 3-Series spark plug wires, ignition wires & components that feature excellent longevity and superior reliability.
