Moroso 27215 Mag-Tune Spiral Core Spark Plug Wire

The Moroso 27215 Mag-Tune Spark Plug Wire is a high-performance ignition wire engineered by Moroso's in-house team using premium materials and advanced manufacturing processes. Designed to deliver maximum energy transmission with minimal interference, this wire is trusted across a wide range of applications — from daily-driven street vehicles to Top Fuel dragsters and NASCAR-level competition.

Key Features:

• Spiral core construction: Stainless nickel alloy conductor wound around a conductive, latex-coated heavy fiberglass core for efficient spark energy delivery
• Superior EMI/RFI suppression: Spiral-wound design significantly reduces electromagnetic and radio frequency interference
• High dielectric strength: Inner insulation layer provides maximum resistance to voltage breakdown
• Dual-layer EPDM outer jacket: Two layers of high-heat-resistant EPDM separated by a nylon reinforcing pull tape for added durability and pull strength
• High-temperature silicone boots: Withstand temperatures up to 600°F to protect connections in demanding engine bay environments
• Snap-lock terminals: Sure-grip, snap-lock spark plug terminals ensure a positive, secure connection
• Moisture resistant: 100% silicone boots seal out moisture and contaminants

Moroso Mag-Tune spark plug wires are fully tested for secure termination, electrical conductivity, and dielectric strength before leaving the factory. Whether you're building a high-horsepower street machine or a dedicated race engine, the Moroso 27215 delivers consistent ignition performance you can count on.
