LS3/L99 8mm Spark Plug Wires (Red)

When upgrading the performance of your GTO, you will want to upgrade your ignition wires to a set of JBA PowerCables™. Each set is custom tailored to your specific application so you get a perfect fit every time. JBA's performance ignition wires feature ultra-low resistance wire-wound mag conductors that allow more spark energy to reach the spark plug without electronic interference. JBA Powercables™ come with 100% silicone jackets for great resistance to high heat as well as abrasion and tears. The high heat boots give plenty of clearance for routing around the headers. The editors at Car Craft made an extra 5 hp on a project engine with a set of 9mm JBA PowerCables™. Installing a set of these wires is easy to do on the GTO and they look great under the hood.
