NGK 52043 Spark Plug Wire Set Silicone SMag Core Ignition Wires

The NGK 52043 spark plug wire set (also called ignition wires or spark plug cables) delivers high-voltage current from the ignition system to the spark plugs. NGK is a leading ignition specialist with decades of OE experience, and this replacement wire set is built to meet OE standards for fit, performance and durability.

Key Features:

• SMag core: a stainless steel winding over a ferrite magnetic core gives low resistance and a strong spark, with EMI/RFI noise suppression
• Silicone outer jacket: high-temperature silicone resists underhood heat of up to 250 °C (482 °F)
• Dual-layer insulation: EPDM/silicone inner insulation with fiberglass-reinforced braiding gives good dielectric strength and cable tensile strength
• Stainless steel terminals for reliable electrical connections
• Silicone-sealed spark plug boots: the boots are sealed to the cable to keep out moisture
• Blue jacket, 8 mm outer diameter, with red spark plug boots and black coil-end boots
• Limited lifetime warranty

Cracked or worn plug wires can cause misfires, rough idle and poor performance. Installing a fresh NGK wire set helps restore smooth, dependable ignition.
