Spark Plug Wires for EFI-Controlled Engines

Spark Plug Wires provide the critical pathway for transferring high-voltage energy from ignition coils to spark plugs, with performance versions offering improved conductivity and reduced electromagnetic interference compared to standard wires. Our selection includes premium wire sets featuring specialized construction techniques and materials designed specifically for high-energy electronic ignition systems. These high-performance wires utilize low-resistance spiral-wound or solid core conductors that minimize energy loss while maintaining proper suppression of radio frequency interference that could disrupt sensitive electronic controls. Superior insulation materials including silicone jackets and EPDM rubber provide excellent heat resistance up to 600°F while maintaining flexibility for proper routing in tight engine compartments. Reinforced terminal connections ensure reliable contact with both coils and spark plugs, with specialized boots that provide proper sealing against moisture and contaminants. Available in universal sets that can be custom-fit as well as pre-cut application-specific sets for popular engines, these wires include proper routing separators and looming to maintain organization and prevent crossfire. For EFI systems with high-energy ignition, quality spark plug wires represent an essential component in the ignition path, ensuring maximum transfer of available energy to the spark plugs for optimal combustion efficiency across all operating conditions.
