The center electrode uses a solid copper core for superior heat dissipation and conductivity, paired with a nickel center electrode tip and a nickel ground electrode set up in a semi-surface discharge configuration. A high-grade alumina silicate ceramic insulator provides strength and efficient heat transfer, while corrosion-resistant trivalent plating on the shell means installation and removal do not require anti-seize compound. Cold-rolled threads help prevent cross-threading and damage to the cylinder head during installation. With a 5,000 ohm resistor built in, the NGK 5881 helps suppress ignition noise while maintaining consistent spark delivery. Each package contains one spark plug with a 5\/8 inch hex for standard plug sockets and wrenches. Always check your engine and maintenance manual to confirm the NGK 5881 (BKR7EKU) is the correct plug for your engine, and install only as recommended by the engine's original equipment manufacturer, since using the wrong plug can reduce performance, hurt fuel economy, or damage the engine.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
