Description

The Granatelli Motor Sports 28-1378S is a set of performance ignition wires designed for specific Chevrolet applications. These 8.00mm diameter, blue wires feature black silicone boots for both the distributor and spark plug ends.

With a solid core conductor style and near 0 ohm resistance, these wires are designed to improve power delivery to the spark plug. The high-temperature silicone boots can withstand temperatures up to 500 degrees F, making them suitable for use with aftermarket headers and turbocharger systems. Installation is straightforward, comparable to replacing factory units.
