NGK 5629 DP7EA-9 Standard Spark Plug Copper Core Heat Range 7

The NGK 5629 (DP7EA-9) Standard Spark Plug is a nickel-alloy, copper-core replacement spark plug. It is built to OE quality for motorcycles, ATVs and powersports engines, and it also suits other small engines that call for a DP7EA-9. NGK Standard plugs have long been an OE staple, and this one gives dependable ignition and smooth running.

Key Features:

• Solid copper core: Carries heat away from the tip and conducts well. It also allows a wide heat range.
• Nickel alloy electrodes: The center electrode has a nickel tip. The ground electrode is a single standard J-gap nickel electrode.
• Alumina silicate ceramic insulator: Gives strong dielectric performance and good heat transfer.
• Trivalent metal plating: Resists corrosion and seizing, so the plug installs and removes more easily.
• Cold-rolled threads: Help prevent cross-threading and cylinder head damage.
• Triple gasket sealing: Helps keep combustion gases from leaking.
• Corrugated insulator ribs: Help prevent flashover.
