Spark Plug Wires

Performance and Technical information on  spark plug wires for Harley-Davidson motorcycles.

The number of performance claims that exist around a simple spark plug wire could lead you to believe that all your performance problems can be solved with the simple purchase of a set of spark plug wires. The claims range from the mildly interesting to completely absurd. When reviewing many of the advertisements for some of these products, a small element of truth may exist in the claim. V-Twin Café believes that most of the claims are based upon before and after testing comprised of aged components compared to the installation of new, high quality components. This is the situation that most consumers will be in when they look for a set of ignition wires.

Since you are reading this article, it must be assumed that you are serious about engine performance and are looking for solid facts. In the July 1997 issue of Hot Rod Bikes (Peterson Publishing Company) pages 72 to 80, a series of dyno runs were conducted on ignition wires from several manufacturers. The results of the test provided V-Twin Café with some interesting discussions with other people in the performance industry. Despite some of the results of the dyno tests by HRB, V-Twin Café believes that claims of increases in performance that seem to good to be true, probably are. With that in mind, an excellent description of spark plug wires and their relationship to spark plugs, the coil and the ignition module were created by Magnecor, a manufacturer of high performance plug wires. V-Twin Café presents this informative information by Magnecor to let you make up your own mind. I can tell you that engines built by Bike Tech do not use any components making claims of 'magic horse power'. While V-Twin Café can not substantiate the claims of increased horsepower by companies like Nology and Splitfire, we feel that engine builders that are serious about increasing the performance of their equipment will do the proper research to make a proper choice.
