Engineered for riders who demand the absolute best from their engine, this plug represents a massive evolution in spark plug performance, designed specifically for high-stress, off-road applications.\u003c\/p\u003e\n\u003cp\u003eAt the heart of this plug is an ultra-small, \u003cstrong\u003efine-wire iridium center electrode\u003c\/strong\u003e. Being 25% smaller than platinum and just 1\/4 the size of a conventional nickel electrode, it significantly reduces the voltage required to create a spark. This not only promotes a more consistent, powerful burn but also helps extend the life of your entire ignition system. Paired with a new, enhanced anti-corrosion shell plating, these plugs are built to survive the most punishing track conditions.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: NGK Iridium Racing Spark Plug\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIridium fine-wire center electrode for maximum durability and performance.\u003c\/li\u003e\n  \u003cli\u003eUltra-small electrode diameter drastically reduces required ignition voltage.\u003c\/li\u003e\n  \u003cli\u003eExtended ignition system service life due to reduced electrical strain.\u003c\/li\u003e\n  \u003cli\u003eAdvanced metal shell plating provides superior anti-corrosion resistance.\u003c\/li\u003e\n  \u003cli\u003ePrecision-engineered non-projected tip for race-specific heat dissipation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease review the detailed compatibility data below to ensure an exact fitment match for your motorcycle before finalizing your purchase.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eFitment List\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #e0e0e0; margin-top: 15px; margin-bottom: 15px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f7f7f7;\"\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eYear Range\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Brand\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Model \u0026amp; Sub-Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2009-2010\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eHonda\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eCRF250R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I gap this plug differently than stock?\u003c\/strong\u003e\u003cbr\u003e\nA: This plug comes pre-gapped at 0.7 mm (0.028\").

Tighten the plug by hand until it seats, then use a torque wrench to reach the manufacturer’s specified torque setting. Over-tightening is a common cause of head thread damage on modern four-stroke engines!\u003c\/p\u003e\n\n\u003ch2\u003eRecommended Pairings\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/honda-crf250r-performance-parts-kits-and-accessories-moto-house-mx\"\u003eHonda CRF250R Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/honda-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eHonda 4-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Motorcycle Shop Tools\u003c\/a\u003e\u003c\/p\u003e\n\n\u003ch2\u003eAbout Moto-House MX\u003c\/h2\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
