FAST Universal Cut-To-Fit FireWire Spark Plug Wire Set

This kit gives you 8 FAST FireWire spark plug wires, ready to be cut to the exact length you need for your engine. The distributor terminals are designed for HEI/Socket style connections, and the spark plug terminals feature a 45-degree angle, making them versatile for many setups. These wires are built from the inside out for performance, especially in racing applications. A key feature is their unique reactive core design, which is really good at filtering out the electro-magnetic interference (EMI) that can cause problems with your ignition control, EFI system, and other electronics. This means you get cleaner operation and less chance of electronic gremlins.

From a performance standpoint, the conductor inside these FireWires has a very low resistance, measuring less than 25 ohms per foot. What that means for you is that more of your spark energy actually makes it to the spark plug gap, ensuring a strong spark for every ignition cycle. To handle the tough environment under the hood, both the core and conductor are wrapped in a double-layered sleeve made of pure silicone. This material is tough against header heat, oils, and general abrasion, and the silicone boots themselves can handle temperatures up to 550°F, so they’re built to last in demanding conditions.
