Mallory Pro Sidewinder plug wires are a premium, universal wire set that include everything needed to build a clean, custom spark plug wire set for your engine. As you'd expect from the trusted Mallory name, the 8mm red silicon jacket withstands temperatures up to 550°F and looks great under the hood. The spiral wound alloy core provides low resistance ensuring maximum energy transfer to the spark plugs while high noise suppression keeps noise interference out of on-board electronics. All this means Mallory Pro Sidewinder Spark Plug Wires are at home on a race engine, hot rod or anything you choose to put them on.
