Moroso 52046 Ultra Spiral Core Ignition Wire Set

The Moroso 52046 is a high-performance ignition wire set from Moroso's trusted Ultra lineup, engineered to deliver consistent, reliable spark energy for street and racing applications. Moroso has decades of experience supplying spark plug wires to top NASCAR and NHRA race teams, and that same technology is built into every Ultra wire set.

Each wire features an efficient spiral-wound conductor constructed with stainless nickel alloy wire wound 32 times per inch around a conductive, latex-coated heavy fiberglass core. This design minimizes radio frequency interference (RFI) while maintaining low resistance for maximum spark energy delivery.

Key Features:

• Spiral-wound stainless nickel alloy conductor — 32 winds per inch around a latex-coated fiberglass core for superior conductivity
• Dual-layer EPDM outer jacket — high heat-resistant layers separated by nylon reinforcing pull tape for added strength and durability
• Optimum dielectric inner insulation — provides exceptional voltage protection and flame resistance
• High-temperature silicone plug boots — protect against extreme engine heat with sure-grip, snap-lock terminals for a positive, secure connection
• 8mm wire diameter — balances performance and fitment for a wide range of applications
• Meets or exceeds OEM specifications for reliable everyday and performance use

The Moroso Ultra wire set is an ideal upgrade or replacement for worn ignition wires, offering race-proven construction at an accessible price point.
