Description

Granatelli spark plug wires utilize an exclusive solid stainless connector cable with stainless snap-lock spark plug connectors and a patented EMI/RFI protection ring. This helps them exhibit near 0 ohm resistance, with RFI/EMI outputs less than OE. These kits increase power to the spark plug by up to 25 percent over stock, and their high-temperature silicone boots resist temperatures of up to 500 degrees F. They're ideal for use with aftermarket headers and turbocharger systems, and installation is as easy as changing the factory units. The assembled wires are engineered to exceed OEM specifications and to be OBD-II computer safe. Order the set designed for your vehicle application.
