New spark plug wires will help restore your BMW 5 Series ignition system to its former glory, giving your ride the performance it deserves. Whether buying OE-spec or aftermarket BMW 5 Series spark plug wires, they are a maintenance item and should therefore be replaced periodically to ensure that your ignition is working at its maximum effectiveness. It's also a good idea to replace your spark plugs at the same time since the wires will already be out of the way.

Improving BMW 5 Series performance can often be accomplished by installing a fresh set of spark plug wires. As your BMW 5 Series spark plug wires deteriorate over time, they become less effective and stop delivering "clean" voltage to your plugs, which results in electromagnetic interference, hesitation, missing, poor idle, and a loss in fuel economy. New BMW 5 Series spark plug wires are available in stock configurations, as well as high-performance versions for increased power, torque, and noise suppression.

Q: How do you install spark plug wires?
A: Spark plug wires take seconds to install. After removing your factory spark plug wires from the valve cover and distributor, you simply replace them with your new ones. 4-cyl motors have 4 spark plug wires; 6-cyl motors have 6 spark plug wires, and so on.

Q: What are spark plug wires? Why purchase spark plug wires?
A: Factory spark plug wires deliver voltage to your spark plugs. Sport spark plug wires deliver a hotter, more powerful, and longer spark to the spark plugs, resulting in more power while reducing the chance for misfires and eliminating radio static.

Q: Are spark plug wires the same thing as ignition wires?
A: Ignition wires are another term used for spark plug wires. They are two terms that mean exactly the same thing.
