Moroso Ultra Race Spark Plug Wires Under Header Non-HEI

Moroso Ultra Race spark plug wires are custom-fit wire sets built for engines that route the plug wires under the headers and use a non-HEI style distributor cap. They suit street/strip, circle track and drag racing builds that need dependable ignition performance. The race-proven construction helps deliver a strong spark and consistent power.

Key Features:

• Made in the USA: Built to meet or exceed auto manufacturer specifications for the application.
• Racing heritage: Moroso has more than 50 years of experience supplying spark plug wires to top NASCAR and NHRA teams.
• Efficient conductor: Stainless nickel alloy wire is wound around a conductive fiberglass core for good spark energy transfer and suppression of radio and electrical interference.
• High-heat jacket: The outer jacket resists heat, which helps in tight, hot engine bays.
• Silicone boots and terminals: Silicone plug boots protect against high heat. Snap-lock terminals give a positive, secure connection.
• Under-header routing: The wire set is made for routing beneath the headers and uses a non-HEI style distributor cap connection.
• Options: The line comes in several wire constructions, with or without exterior sleeving for extra protection against header heat, chafing and contaminants.

Moroso Ultra Race wire sets give a professional, tidy ignition installation. They are a durable upgrade over worn or heat-damaged plug wires.
