Granatelli Hi-Performance Spark Plug Wires exhibit near 0-ohm resistance with RFI/EMI outputs less than O.E. because they utilize an exclusive solid stainless connector cable with stainless snap lock spark plug connectors and a unique EMI/RMI protection ring.

Granatelli's wires increase power to the spark plug up to 25% over stock, an amazing accomplishment. High temperature silicone boots and a 8MM jacket with fiberglass reinforced braid resists temperatures up to 500 degrees f. (ideal for use with aftermarket headers and turbocharger systems). Installation is as easy as changing the factory units. Engineered to exceed OEM specifications and be OBD-II computer safe, they will not void your factory powertrain warranty.

Great fit for your LT1 powered car.
