NGK 51173 RC-GMX045 Spark Plug Wire Set, 5mm Magnetic Core Silicone

The NGK 51173 (RC-GMX045) spark plug wire set, also called ignition wires or plug leads, is a direct-replacement ignition cable set. It carries high-voltage current from the ignition system to the spark plugs. It is built to meet or exceed OE specifications, so it restores dependable ignition performance.

Key Features:

• 5mm ultra-low resistance magnetic core: wire-wound construction delivers a strong spark and good noise suppression.
• Variable pitch wire winding: helps suppress EMI/RFI interference.
• High-temperature silicone jacket: resists underhood temperatures up to 482°F (250°C).
• Fiberglass braid reinforcement: high-density braiding over EPDM/silicone inner insulation adds dielectric strength and cable tensile strength.
• Stainless steel terminals: positive-locking, corrosion-resistant ends resist vibration and separation.
• OE-spec boots: spark plug and distributor boots are specified to OEM or better, with a silicone seal at the spark plug.
• Easy installation: wires are numbered for cylinder identification, and the coil wires are color coded.

NGK is The Ignition Specialist, with decades of OE experience in spark plugs, ignition coils and wire sets. This wire set is a durable replacement for worn or cracked ignition wires that cause misfires, rough running or poor fuel economy.
