Wired Harnesses 55442 Spark Plug Wire Set

The Wired Harnesses 55442 is a replacement spark plug wire set designed to restore reliable ignition performance. Spark plug wire sets — also called ignition wire sets or high-tension leads — carry the high-voltage electrical pulse from the distributor or ignition coil to each spark plug, ensuring a strong, consistent spark for complete combustion.

Key Features:

• Complete spark plug wire set for full ignition system replacement
• High-dielectric insulation to prevent misfires and cross-firing between cylinders
• Suppression core construction helps reduce electromagnetic interference (EMI) with onboard electronics
• Boots and terminals designed for secure, corrosion-resistant connections at the plug and coil/distributor ends
• Direct replacement fitment for hassle-free installation

Worn or cracked plug wires are a common cause of engine misfires, rough idle, poor fuel economy, and hard starting. Replacing the full set at once ensures uniform ignition performance across all cylinders and is a standard part of a routine tune-up.
