Speedmaster Universal Silicone Spark Plug Wires

Speedmaster Universal Silicone Spark Plug Wires are ignition wire sets built to deliver more spark from your plugs. They suit performance builds, street rods, and engine upgrades. The high-temperature silicone insulator and spiral-wound copper conductor give strong energy transfer to the spark plugs while controlling electrical noise. These ignition wires also work as aftermarket replacement plug wires.

Key Features:

• High-temperature silicone insulation: The outer layer is 100% pure silicone, which resists underhood heat and abrasion.
• Spiral-wound copper conductor: It has very low resistance, so more energy reaches the spark plugs.
• RFI/EMI suppression: It helps limit interference with onboard electronics such as radios and engine management components.
• Durable construction: A high dielectric strength insulator and heavy glass braid sit under the silicone jacket.
• Silicone boots: High-temperature boots at the distributor and spark plug ends protect against heat damage.
• Universal design: The wires come in a range of boot angles, distributor terminal styles, and finishes to suit different engine layouts.

Speedmaster designs these wires for enthusiasts who want reliable ignition performance and a clean look in the engine bay. They get the most out of ignition upgrades such as high-output coils and performance distributors.
