Factory ignition wires on high-output engines like the 7.3L Godzilla handle the basics, but they leave performance on the table. Moroso's Ultra 8mm spark plug wire set replaces those factory wires with a purpose-built conductor engineered for reliable spark delivery, heat resistance, and minimal electrical interference. With 135-degree boots and a clean black jacket, this set fits the 7.3L without clearance fights or awkward routing.
A conductor built for serious electrical demands. Each wire uses a stainless nickel alloy conductor wound 32 times per inch around a conductive, latex-coated heavy fiberglass core. That spiral-wound construction keeps resistance consistent at 350 ohms per foot while suppressing electromagnetic interference that can disrupt modern engine management sensors and electronics.
Layered construction for extreme-heat environments. The outer jacket combines two layers of high-heat resistant EPDM rubber separated by a nylon reinforcing pull tape. That pull tape absorbs the stress of removal so it never transfers to the wire itself. An inner insulation layer adds dielectric strength, while the outer jacket handles direct heat exposure and flame contact without cracking or degrading.
Silicone boots lock in and hold tight. Each 135-degree silicone plug boot encases a sure-grip, snap-lock terminal that seats positively on the spark plug and resists vibration-induced loosening. Silicone construction keeps the boot pliable in high-heat areas where rubber alternatives harden and crack over time.
Product Benefits
- 8mm Ultra Construction: Stainless nickel alloy conductor wound 32 times per inch for consistent resistance and EMI suppression.
- 350 Ohms Per Foot: Controlled resistance protects ignition components while delivering a strong, reliable spark.
- Dual-Layer EPDM Jacket: Two heat-resistant layers separated by nylon pull tape resist heat, flame, and mechanical stress.
- Inner Dielectric Layer: Added insulation prevents voltage leakage and cross-fire between adjacent wires.
- 135-Degree Silicone Boots: Angled design clears tight spaces on the 7.3L Godzilla without forcing awkward bends.
- Snap-Lock Terminals: Sure-grip design seats securely and resists loosening from engine vibration.
- Black Unsleeved Finish: Clean, low-profile appearance under the hood.
Note: Fits Ford 7.3L Godzilla V8 applications.
