NGK 53188 Spark Plug Wire Set RC-CRX070S 7mm Silicone Carbon Core

The NGK 53188 spark plug wire set (also listed as RC-CRX070S), sometimes called ignition wires or spark plug cables, carries high-voltage current from the ignition system to the spark plugs. It is built to OE-style specifications for dependable ignition performance and low electrical noise.

Key Features:

• Six-lead set (coil lead N/R) with application-specific boots for a precise fit
• 7mm distributed-resistance, carbon-suppression core cable that reduces EMI/RFI interference
• High-temperature silicone jacket resists underhood temperatures up to 482°F (250°C)
• Fiberglass braid reinforcement over EPDM/silicone inner insulation for dielectric strength and cable tensile strength
• Variable-pitch wire winding for effective noise suppression
• Stainless steel terminals with positive-locking, corrosion-resistant design that resists vibration and separation
• Silicone-sealed spark plug boots help keep moisture out
• Numbered leads make cylinder identification easier during installation
