It carries the NGK BPR7ES designation and is treated with corrosion-resistant plating so it installs and removes cleanly without seizing in the cylinder head. At the core is a solid, 98% pure copper center electrode that improves heat dissipation and conductivity, helping the plug fire consistently and resist overheating under load. A high-grade alumina silicate ceramic insulator provides strength and efficient heat transfer, while cold-rolled threads reduce the risk of cross-threading during installation. Corrugated ribs on the insulator help prevent flashover, and the trivalent plating means no anti-seize compound is required at install. The plug uses a standard ground configuration with a nickel ground electrode and nickel center electrode tip, and carries a resistance rating of 5000 Ohm to help suppress ignition noise. NGK Standard plugs like the 5534 have served as an OE cornerstone across marine and powersport engines for decades. This part is listed for 1985-2001 Johnson outboard motors and 1984-1988 Tanaka outboard engines; always check your engine's maintenance manual to confirm the correct plug before ordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 5534\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Type Designation:\u003c\/strong\u003e BPR7ES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295155349\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 14mm x 1.25mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance:\u003c\/strong\u003e 5000 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Configuration:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode Core Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Core Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Electrode Tip Material:\u003c\/strong\u003e Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulator Material:\u003c\/strong\u003e High-grade alumina silicate ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlating:\u003c\/strong\u003e Trivalent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 spark plug per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson outboard motors, 1985-2001\u003c\/li\u003e\n\u003cli\u003eTanaka outboard motors, 1984-1988\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e2023\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the NGK 5534 spark plug?\u003c\/strong\u003e The NGK 5534 is a standard nickel spark plug carrying the NGK BPR7ES type designation, built with a solid copper core center electrode for reliable heat dissipation and conductivity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the NGK 5534 fit a Johnson outboard motor?\u003c\/strong\u003e Yes, the NGK 5534 (BPR7ES) is listed for 1985-2001 Johnson outboard motors.
