Key Features

• Terminal design: Solid boot type with corrosion-resistant terminals improves spark plug retention and eases installation by giving a firm connection at both ends.
• Insulation quality: The insulator uses high dielectric materials to resist arcing and interference for stable ignition performance.
• Vehicle coverage: Designed to cover over 96% of domestic vehicles, providing broad compatibility for many GM, Chrysler, Ford, and other domestic applications.

Who It's For

This wire set is ideal for owners of GM vehicles and many domestic cars and trucks who want a premium aftermarket part that closely matches the original equipment fit and function.
