Performance spark plug cables (also known as high-performance ignition wires) are upgraded versions of stock spark plug wires, designed to deliver a stronger, more consistent spark — crucial for high-performance or modified engines.

Key Benefits of Performance Spark Plug Cables:
Better Conductivity
Made with materials like low-resistance spiral core wire or Kevlar core, they transmit more energy to the spark plug.

Higher Heat & Voltage Tolerance
Ideal for turbocharged, supercharged, or high-revving engines where higher temps and voltages are common.

EMI/RFI Suppression
Reduced electromagnetic interference protects sensitive electronics (especially in modern cars).

Durability
Silicone or high-temp materials withstand under-hood conditions better than OEM rubber cables.
