NGK (9731) RC-HE39 Spark Plug Wire Set

NGK Wire Set: 7mm ultra-low resistance magnetic core, wire wound ignition cable with OEM or better specified spark plug and distributor boots.

High temp silicone jacket resists underhood temperatures up to 482 degrees F.

High density, premium fiberglass braiding reinforcement over EPDM / silicone inner insulation for superior dielectric strength and excellent cable tensile strength.

NGK wire sets are built to meet stringent OEM tolerances for a variety of vehicles.

They utilize a construction method known as variable pitch wire winding to create resistance to radio frequency interference.

The variable pitch winding provides suppression throughout a very wide range by scrambling and breaking up the electrical waves radiated by the firing of the spark plugs.

NGK wire sets provide superior firing and fuel savings, outstanding durability, excellent noise suppression, and consistent performance.
