LMMF 3100 / 3400 / 3800 Extended Length HD Plug Wires – 36” High Performance Racing Wire Set (Set of 6)If you’re looking for quality and durability, the LMMF 3100/3400/3800 Extended Length HD Plug Wires are a top choice for high performance vehicles.
Built for engine swaps, coil relocation, and extreme racing conditions, the LMMF Extended Length HD Plug Wires deliver the durability and flexibility needed for serious builds. Designed specifically for GM 3100, 3400, and 3800 engines. 36-inch high-performance spark plug wires give extra length required for custom coil pack mounting and clean engine bay routing.
Short factory wires limit where you can mount your coils, extended-length racing wires allow builders to relocate coil packs to the firewall, custom brackets, or other protected areas. This maintains strong spark delivery and reliable ignition performance.
Built with heavy-duty insulation and performance-grade boots, these wires are engineered to handle high voltage, extreme temperatures, and the vibration found in demolition derby and race builds.
