• Fiberglass reinforcement improves tensile strength and durability.
• Solid-style boots form a dependable water-tight seal.
• Corrosion-resistant terminals maintain conductivity under exposure.

How does this set support consistent ignition performance?

Conductor size, length, and diameter are calibrated to deliver efficient spark energy to each cylinder, reducing misfires and maintaining throttle response. The terminal and boot geometry supports firm retention on spark plugs and distributors or coils for reliable operation.

• Optimized conductor dimensions for maximum spark delivery.
• Terminal design improves plug retention and ease of installation.
• Insulator materials maintain stable voltage and reduce leakage.
