Engineered with a precision laser-welded iridium center electrode, this premium plug provides a highly concentrated, consistently stable spark. This translates directly to crisper throttle response, improved fuel efficiency, and significantly easier cold-weather starting. Because the ultra-hard iridium alloy is exponentially more durable than standard copper or platinum, this plug maintains its precise gap over a much longer service life, guaranteeing thousands of miles of dependable combustion in harsh, high-revving environments.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"4\"\u003eFeatures:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"5\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"5,0,0\"\u003eLaser-Welded Iridium Electrode:\u003c\/b\u003e The ultra-fine iridium center electrode ensures a highly focused spark, drastically reducing the voltage requirement placed on the ignition coil and preventing misfires under heavy engine loads.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,1,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"5,1,0\"\u003eSuperior Anti-Fouling:\u003c\/b\u003e Features an advanced alumina silicate ceramic insulator and specialized thermo-edge design that prevents carbon buildup and wet-fouling during low-speed, technical riding.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,2,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"5,2,0\"\u003eExtended Service Life:\u003c\/b\u003e The extreme melting point of iridium minimizes electrical wear and electrode degradation, offering much longer intervals between plug changes compared to standard OEM plugs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,3,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"5,3,0\"\u003eCrisper Throttle Response:\u003c\/b\u003e A more complete and efficient combustion cycle yields immediate roll-on power and a smoother idle.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,4,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"5,4,0\"\u003eTrivalent Metal Plating:\u003c\/b\u003e The threaded body features NGK's proprietary anti-corrosion and anti-seizing plating, protecting delicate aluminum cylinder heads during installation and removal.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eSpecs:\u003c\/span\u003e\u003cbr\u003e\n\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eThread Size: 10mm x 1.0mm\u003c\/li\u003e\n\u003cli\u003eReach: 26.5mm\u003c\/li\u003e\n\u003cli\u003ePre-Set Gap: 0.9mm (0.036\")\u003c\/li\u003e\n\u003cli\u003eHex Size: 14mm wrench\u003c\/li\u003e\n\u003cli\u003eHeat Range: 8 (NGK scale)\u003c\/li\u003e\n\u003cli\u003eElectrode Material: Iridium\u003c\/li\u003e\n\u003cli\u003eResistor Plug: Yes (Suppressed)\u003c\/li\u003e\n\u003cli\u003eSolid terminal\u003c\/li\u003e\n\u003cli\u003eNGK Part Number: 91909\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch4\u003e2019–2026 – Yamaha Tenere 700\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e2024–2026 – CFMOTO Ibex 450 \/ MT450\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e2023–2026 – Suzuki V-Strom 800DE\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003ch4 style=\"text-align: center;\" data-end=\"1205\" data-start=\"1125\"\u003eAlways verify fitment with your motorcycle’s \u003cbr\u003eservice manual before installation. \u003cbr\u003eEmail us at \u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003e\u003ca href=\"mailto:tmbrmoto@tmbrmoto.com\" title=\"Email TMBR MOTO with questions about spark plugs and any parts and accessories needs.\" rel=\"noopener\" target=\"_blank\"\u003e\u003cspan style=\"color: rgb(215, 65, 35); text-decoration: underline;\"\u003eTMBRMOTO@TMBRMOTO.COM\u003c\/span\u003e\u003c\/a\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003eif you have any questions\u003c\/h4\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/MADE_IN_JAPAN.jpg?v=1744046245\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003ePart Number: 91909\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"NGK","offers":[{"title":"Default Title","offer_id":47869971726501,"sku":"NGK-LMAR8BI-9","price":22.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/NGK_Spark_Plug_LMAR8BI-9.webp?v=1780274344","url":"https:\/\/www.tmbrmoto.com\/products\/ngk-spark-plug-lmar8bi-9","provider":"TMBR MOTO","version":"1.0","type":"link"}
