NGK 52306 Spark Plug Wire Set RC-FDZ023 Blue Silicone Magnetic Core 8mm

The NGK 52306 spark plug wire set (also called an ignition wire set or spark plug cable set, NGK stock code RC-FDZ023) is a replacement set built to OEM tolerances. It carries high-voltage current from the distributor or coil to each spark plug. Worn or cracked wires can cause misfires, rough idle and weak spark, so replacing them helps restore dependable ignition performance.

Key Features:

• 8mm ultra-low resistance ferrite magnetic core with stainless steel winding for a stronger spark and excellent EMI/RFI noise suppression
• Variable pitch winding (loose to tight to loose) breaks up radio frequency and electromagnetic interference that can affect on-board electronics
• High-temperature silicone outer jacket rated to withstand temperatures above 250 degrees Celsius
• Inner EPDM/silicone insulation for high dielectric strength
• Silicone spark plug boots are glued to the cable with silicone sealer for a watertight seal; boots are 180 degree and angled styles as specified for the application
• Stainless steel terminals with serrated crimps that grip the cable jacket and insulation for strong retention
• Locking C-shaped spring clip with corrosion-resistant plating for a secure spark plug terminal connection
• Blue wire color; wire separators are not included
• Backed by a 1 year limited warranty
