The copper core promotes efficient heat dissipation and strong conductivity, helping the plug deliver a consistent spark across a broad heat range. Corrosion-resistant plating on the shell and threads makes installation and removal straightforward, reducing the risk of the plug seizing in the cylinder head over time.\u003c\/p\u003e\u003cp\u003eThis is a resistor-type plug rated at 5,000 Ohm, which helps suppress electrical interference from the ignition system. It uses a standard ground electrode configuration with a nickel ground electrode and a nickel center electrode tip, backed by the copper core for heat transfer. The plug is sized with a 14mm shell thread and a 13\/16 inch hex, and is sold as a single spark plug per order.\u003c\/p\u003e\u003cp\u003eAlways check your engine's maintenance manual to confirm the BPR6ES \/ NGK 7131 is the correct plug for your engine, and use only the plug type recommended by your engine's original equipment manufacturer. Installing the wrong spark plug can reduce performance, lower 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 NGK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 7131\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNGK Model Designation:\u003c\/strong\u003e BPR6ES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Standard Spark Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell Thread Size:\u003c\/strong\u003e 14mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size:\u003c\/strong\u003e 13\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpark Plug Gap:\u003c\/strong\u003e 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistor:\u003c\/strong\u003e Yes, 5,000 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround Electrode 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\u003eQuantity:\u003c\/strong\u003e 1 spark plug per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 087295171318\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is NGK part number 7131?\u003c\/strong\u003e NGK part number 7131 is the NGK BPR6ES, a standard resistor-type spark plug with a copper core and nickel-plated electrodes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the NGK BPR6ES a resistor spark plug?\u003c\/strong\u003e Yes, the NGK BPR6ES (part number 7131) is a resistor-type plug rated at 5,000 Ohm, which helps suppress ignition system interference.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the hex size for a wrench or spark plug socket?\u003c\/strong\u003e The NGK BPR6ES uses a 13\/16 inch hex, so a standard 13\/16 inch spark plug socket is needed for installation and removal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the shell thread size on this spark plug?\u003c\/strong\u003e The NGK 7131 \/ BPR6ES has a 14mm shell thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs are included?\u003c\/strong\u003e The NGK BPR6ES (part number 7131) is sold as a single spark plug per unit, not as a multi-pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the factory gap setting on this plug?\u003c\/strong\u003e The NGK BPR6ES ships with a 0.04 inch spark plug gap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat materials are used in the electrodes?\u003c\/strong\u003e The NGK 7131 uses a copper core electrode with a nickel center electrode tip and a nickel ground electrode for heat dissipation and durability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine NGK spark plug?\u003c\/strong\u003e Yes, the NGK BPR6ES (part number 7131) is a genuine NGK standard spark plug, not an aftermarket clone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat warranty comes with the NGK BPR6ES?\u003c\/strong\u003e The NGK BPR6ES is covered by a warranty against defects in material or workmanship for 12 months or 12,000 miles, whichever comes first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the NGK 7131 spark plug weigh?\u003c\/strong\u003e The NGK BPR6ES (part number 7131) weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the BPR6ES is the right plug for my engine?\u003c\/strong\u003e Check your engine's maintenance manual for the recommended spark plug type before installing the NGK BPR6ES, since using the wrong plug can reduce performance, lower fuel economy, or damage the engine.\u003c\/p\u003e","brand":"NGK Spark Plugs","offers":[{"title":"Default Title","offer_id":49028253384923,"sku":"NGK-BPR6ES","price":3.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/NGK-BPR6ES-Spark-Plug__15145.1722492320.500.750.jpg?v=1785165221","url":"https:\/\/www.goodvibesmarina.com\/products\/ngk-7131-bpr6es-spark-plug-standard-copper-core-marine-spark-plug","provider":"Good Vibes Marina","version":"1.0","type":"link"}
