Through a proprietary jacketing formulation, PowerMAX spark plug wire provides the best combination of both heat resistance and abrasion resistance on the market today.

PowerMAX spark plug wires have a proprietary, protective coating that is bonded to a flexible, durable silicone compound. The result is a wire that is able to withstand heat exceeding 600° F and has outstanding abrasion resistance.

The enhanced core design maximizes the energy flow through an exclusive construction and coating process, resulting in improved engine performance and efficiency.

Verified by an independent testing facility, PowerMAX wire consistently delivered more than 90 percent conductivity. PowerMAX spark plug wire either meets or exceeds the original equipment design specifications.
