NGK 3579 Standard Spark Plug BZ7HS-10, Copper Core, Nickel Electrode

The NGK 3579 is a Standard series spark plug built to the BZ7HS-10 design, using proven copper-core construction for reliable, consistent ignition. NGK Standard plugs are treated with corrosion-resistant plating on the shell and threads, which makes installation and removal easier and helps prevent seizing over time. At the core of the plug is a solid copper center, chosen because it offers superior heat dissipation and conductivity along with a broad heat range, so the plug can handle varying load and RPM conditions without pre-ignition or fouling.

The electrode setup on the NGK 3579 pairs a nickel ground electrode with a nickel-tipped copper center electrode in a standard ground configuration, and the plug carries 35 ohms of resistance to help suppress ignition noise. The hex size is 13/16 inch, matching standard spark plug sockets. NGK positions this Standard line as an OE-cornerstone product, reflecting the same basic design and materials used in original-equipment applications for decades. Always confirm the correct spark plug against your engine's maintenance manual, since installing the wrong plug can reduce performance and fuel economy or cause engine damage.

Frequently Asked Questions

What is the part number for this NGK spark plug? The part number is NGK 3579, built to the BZ7HS-10 spark plug design.

What material is the center electrode made of? The NGK 3579 uses a solid copper center electrode core with a nickel tip, which provides strong heat dissipation and conductivity.

What is the ground electrode made of on the NGK 3579? Nickel is used for the ground electrode, paired with a standard ground configuration on the NGK 3579.

What hex size wrench or socket do I need to install this plug? 13/16 inch is the hex size for the NGK 3579 spark plug, matching a standard spark plug socket.

Does the NGK 3579 have built-in resistance for ignition noise suppression? Yes, the NGK 3579 carries 35 ohms of resistance.

Is the NGK 3579 a genuine NGK part or an aftermarket equivalent? The 3579 is a genuine NGK Standard series spark plug, part of NGK's original OE-cornerstone plug lineup rather than a third-party equivalent.

How does the plating on the NGK 3579 help with installation? The NGK 3579 is treated with corrosion-resistant plating on the shell, which makes it easier to install and remove without seizing in the cylinder head.

Why does NGK use a copper core in the Standard series plugs like the 3579? A solid copper core is used in the NGK 3579 because it offers superior heat dissipation, conductivity, and a broad heat range compared to a plain steel core.

What does the ground configuration on the NGK 3579 mean? Standard ground configuration on the NGK 3579 means the ground electrode is a single fixed post design rather than a surface-discharge or multi-electrode design.

How much does the NGK 3579 spark plug weigh? The NGK 3579 spark plug weighs 0.15 pounds.

How do I know if the NGK 3579 is the correct plug for my engine? Always check your engine's maintenance manual for the recommended spark plug before installing the NGK 3579, since using the wrong plug can reduce performance and fuel economy or cause engine damage.
