Wired Harnesses 55766K Spark Plug Wire Set

The Wired Harnesses 55766K is a replacement spark plug wire set designed to restore reliable ignition performance. Spark plug wire sets carry the high-voltage electrical signal from the ignition coil or distributor to each spark plug, and worn or degraded wires can result in misfires, rough idling, reduced fuel economy, and poor engine performance.

Key Features:

• Direct-replacement spark plug wire set engineered to OE specifications
• Designed to deliver consistent, high-voltage signal transfer to spark plugs
• Heat-resistant boots and jackets protect against engine compartment temperatures
• Suppression winding helps minimize electromagnetic interference (EMI) with onboard electronics
• Corrosion-resistant terminals ensure a secure, reliable connection at both the coil and plug ends

This plug wire set is a straightforward, bolt-on replacement for vehicles requiring part number 55766K. Cross-reference OEM numbers include 55766 and 9663K. Restoring your spark plug wires is one of the most effective and affordable ignition tune-up steps to maintain smooth engine operation.
