FAST Small Block Chevrolet Under-Header Cover FireWire Spark Plug Wire Set

This is the FAST FireWire Spark Plug Wire Set, designed specifically for Small Block Chevrolet engines with under-header cover applications. If you're looking to get the most spark energy to your plugs, especially in a performance or racing setup, these wires are built for the job. They feature a unique reactive core that effectively suppresses electromagnetic interference (EMI), which is crucial for trouble-free operation of your ignition control, EFI system, and other electronics. This is important because a high-powered ignition system needs clean voltage to perform its best.

What sets these wires apart is their extremely low resistance, measuring less than 25 ohms per foot. This means less energy is lost along the wire, ensuring that the maximum possible spark energy makes it to the spark plug gap for a stronger, more efficient burn. To handle the tough conditions under the hood, the core and conductor are wrapped in a double-layered pure silicone sleeve. This material is tough against header heat, oils, and abrasion, and the silicone boots are rated to withstand temperatures up to 550°F, making them a solid choice for demanding engine bays.

This set includes 8 wires, featuring HEI distributor terminals and 90-degree spark plug terminals, designed to fit a wide range of vehicles including many Chevrolet, Buick, and Cadillac models from the 1980s and 1990s. Always check the full fitment guide to confirm compatibility with your specific application.
