Karlyn/STI has engineered a wire set line that is second to none in every aspect of performance, protection and coverage. We utilize German Engineered Spark Plug Connectors, specially designed durable boots, corrosion resistant and oversized clip-lock terminals which allow for positive electrical connection every time you install or reinstall them. Our 8.0mm Silicone-over-Silicone cable includes two layers of Silicone for superior voltage protection and we use stainless steel magnetic conductive windings for applications which can handle extra fire power to reach the spark plugs. This results in improved gas mileage and superior engine performance, while it prevents radio frequency noise from interfering with radios, cellular telephones, TVs, computers and other onboard electronic equipment. Every set is Proudly Assembled in the USA and is 100% tested for conductivity and proper resistance before packaging.
