Moroso Ultra Series Black Universal Spark Plug Wire Set

The Moroso Ultra Series Universal Spark Plug Wire Set (also called ignition wires or plug wires) is a performance-minded, cost-effective way to refresh your ignition system. Ultra wires are made in the USA. They are designed to equal or exceed auto manufacturer specifications for the application, and they are built to support strong spark delivery on daily drivers, street/strip builds, and performance cars and trucks.

Key Features:

• Spiral-core construction: A stainless nickel alloy conductor is wound around a conductive, latex-coated fiberglass core. This gives dependable ignition performance with radio-frequency interference suppression.
• Durable dual-layer jacket: Two layers of high-heat-resistant EPDM are separated by a nylon reinforcing pull tape for added pull strength.
• Heat and flame protection: The inner insulation layer provides dielectric strength. The outer jacket resists high heat and flame.
• Silicone plug boots: The boots protect against high-heat situations. They enclose sure-grip, snap-lock terminals for secure, positive connections.
• Universal, cut-to-length design: Sets are offered in universal configurations so you can tailor the routing and installation to your engine.
• Range of options: The Ultra line offers different cylinder counts, boot angles, and distributor terminal styles to suit a wide range of engine builds.

Moroso has more than 50 years of experience supplying ignition wires to top NASCAR and NHRA teams and to automotive manufacturers. Ultra Series wires bring that experience to street and performance applications. Moroso also offers the line in custom-fit sets and with optional exterior sleeving for additional heat protection.
