NGK 54393 RC-EUX004 Spark Plug Wire Set, Mag Core Silicone

The NGK 54393 spark plug wire set (also called ignition wires or plug leads, NGK series RC-EUX004) carries high-voltage current from the ignition system to each spark plug. It is built to OE tolerances for dependable spark delivery and engine performance.

Key Features:

• Ultra-low resistance mag core: stainless steel winding over a ferrite magnetic core gives a stronger spark and good EMI/RFI noise suppression.
• High-temperature construction: a premium silicone outer jacket withstands temperatures above 250°C. The inner EPDM/silicone insulation gives excellent dielectric strength.
• Silicone insulation: blue, with a 7.00 mm outside diameter.
• Watertight boots: OE-spec spark plug and distributor boots are glued to the cable with silicone sealer.
• Stainless steel terminals: serrated crimps grip the cable jacket and inner insulation for strong terminal retention.
• Locking spring clip: a C-shaped, corrosion-resistant clip secures the spark plug terminal connection.
• Cylinder lead ID tags: where possible, tags make installation easier.
• Configuration: 6 wires, including 2 coil leads.
• Warranty: limited lifetime warranty. See the package for details.
