NGK 55030 Spark Plug Wire Set Silicone Ferro Mag Core 5mm RC-MX107

The NGK 55030 spark plug wire set (also called ignition wires or spark plug cables) carries high-voltage current from the ignition system to the spark plugs. It is built to OE tolerances for a precise fit and dependable ignition performance. This set is also listed under NGK part number RC-MX107.

Key Features:

• Ferro-mag core: A stainless steel winding over a ferrite magnetic core gives low resistance, a stronger spark, and effective EMI/RFI noise suppression.
• Silicone construction: The high-temperature silicone outer jacket withstands temperatures above 250°C. EPDM or silicone inner insulation provides strong dielectric strength.
• Wire diameter: 5 mm.
• Silicone boots: Black silicone spark plug and coil boots are glued to the cable with silicone sealer for a watertight seal. Boots are 180° (straight).
• Stainless steel terminals: Up to 3 serrated crimps bite into the jacket and insulation for strong terminal retention.
• Locking spring clip: A corrosion-resistant plated C-shaped clip keeps the spark plug terminal connection secure.
• Cylinder lead ID: Identification tags, where possible, make installation easier.
