409 Spiro-Pro custom blue

The Taylor Wire / Vertex 79681 is a performance-grade spark plug wire set designed for 1987-96 GM Small Block engines with Throttle Body Injection. These 10.4mm wires feature a 409 Series construction with a helically wound, highly conductive core and a silicone inner core for added heat protection and flexibility.

With 350 ohms per foot resistance, these wires aim to deliver more energy to the spark plugs, potentially increasing horsepower and torque while improving fuel mileage. The outer silicone jacket is rated for up to 65,000 volts and is heat resistant to 600° Fahrenheit, making them suitable for high-heat applications.
