FAST Firewire Cut-To-Fit Cylinder Spark Plug Wire Set

The FAST FireWire Cut-To-Fit Spark Plug Wire Set is a universal-style ignition wire set. You trim each wire to the length your engine needs. That gives a clean, tidy installation and avoids the excess wire of fixed-length sets. Other names for it include custom-fit spark plug wires, universal plug wires, and ignition wire set.

Key Features:

• Cut-to-fit design lets you size each wire for your engine bay and routing
• Built to carry spark energy from the coil or distributor to each spark plug
• Designed to help suppress electrical interference (EMI/RFI) that can disrupt ignition and onboard electronics
• Insulated, high-temperature jacket helps protect the wire from engine heat and under-hood conditions
• Terminal and boot hardware are included for building a complete set
• Backed by FAST (Fuel Air Spark Technology), a name in performance ignition and fuel systems

Cut-to-fit wires suit custom builds, engine swaps, and performance applications where stock-length wires don't fit well. A properly sized wire set helps keep the spark path consistent for smooth starts, steady idle, and reliable running. Several versions are offered in this product line. Choose the one that matches your engine and ignition setup.
