FAST GM Circle Track Wire Set With Heat Sleeve Firewire Spark Plug Wire Set

When you're building a high-powered ignition system for your GM Circle Track engine, getting that spark energy to the plug reliably is key. These FAST FireWire spark plug wire sets are built from the inside out to handle the demands of performance and racing. They're designed to effectively filter out the electro-magnetic interference, or EMI, that can cause problems with your ignition control, EFI, and other electronics. This is thanks to a unique reactive core design that suppresses that noise.

From a performance standpoint, the conductor in these FireWires has a very low resistance, less than 25 ohms per foot. What that means for you is less resistance means more spark energy actually makes it to the spark plug gap for a stronger, more consistent spark. To protect against the harsh conditions under the hood, like header heat, oil, and abrasion, the core and conductor are wrapped in a double-layered pure silicone sleeve. The silicone boots themselves can handle temperatures up to 550 degrees Fahrenheit, making these a solid option for demanding applications.

This set includes 8 wires, and the spark plug boots are a 90-degree style, which helps with routing in tight engine bays. They also come wrapped in a heat sleeve for added protection against radiant heat.
