NGK 51223 Spark Plug Wire Set - Ignition Wires

The NGK 51223 spark plug wire set is an OE-quality replacement ignition wire set (also called spark plug cables or ignition leads). It carries high-voltage current from the distributor or coil to the spark plugs. Worn or cracked wires can cause misfires, rough idle and hesitation, so replacing them restores reliable ignition.

Key Features:

• Engineered to meet strict OEM tolerances for fit and performance
• Variable pitch wire winding resists radio frequency interference (RFI/EMI) and suppresses noise
• High-temperature silicone outer jacket, with inner EPDM or silicone insulation for strong dielectric strength
• Stainless steel terminals grip the cable jacket and inner insulation for strong terminal retention
• Numbered cylinder lead labels make installation easier
• Spark plug boots are sealed to the cable for a watertight connection

NGK has decades of OE experience in ignition. It is a trusted name in spark plugs, ignition coils, coil-on-plug boots and wire sets for domestic and import vehicles.
