The KTM Factory Spark Plug SXS 12502 is engineered precisely for that environment, delivering consistent, high-energy ignition across the full rev range whether you are chasing lap times on the circuit or navigating demanding enduro terrain. This is the factory-recommended plug, built to the same specification as the components fitted to KTM's own competition machines.\u003c\/p\u003e\n\u003cp\u003eThe iridium-tipped centre electrode is the defining feature of this plug. Iridium's exceptional hardness and conductivity produce a sharper, more focused spark than standard copper or platinum alternatives, translating directly into improved combustion efficiency and crisper throttle response. Complementing this is a reinforced ground electrode, purpose-designed to absorb the intense vibration loads that high-revving KTM engines generate, significantly reducing the risk of breakage or premature failure under race conditions.\u003c\/p\u003e\n\u003cp\u003eA specially engineered anti-sooting design keeps the electrode cleaner for longer, sustaining reliable ignition performance even during low-speed running or cold starts where fouling is most likely to occur. KTM recommends pairing this plug with factory cylinder heads, factory exhaust systems, or a factory digital ignition box to ensure every element of the ignition and combustion system works in concert for maximum power and dependability.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eIridium centre electrode tip\u003c\/li\u003e\n\u003cli\u003eReinforced ground electrode designed to resist vibration-induced breakage\u003c\/li\u003e\n\u003cli\u003eImproved anti-sooting design \u003c\/li\u003e\n\u003cli\u003eExtremely robust construction built to factory specification\u003c\/li\u003e\n\u003cli\u003eRecommended for use with KTM factory cylinder heads, factory exhaust systems, and factory digital ignition boxes\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFits\u003c\/h5\u003e\n\u003cp\u003eThis spark plug is compatible with the following KTM motorcycle models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e125 SX 2000-2027\u003c\/li\u003e\n\u003cli\u003e125 SX Tyla Rattery 2005\u003c\/li\u003e\n\u003cli\u003e125 SXS 2000-2008\u003c\/li\u003e\n\u003cli\u003e125 XC 2021-2022\u003c\/li\u003e\n\u003cli\u003e144 SX 2007-2008\u003c\/li\u003e\n\u003cli\u003e150 SX 2009-2025\u003c\/li\u003e\n\u003cli\u003e150 XC 2010-2013\u003c\/li\u003e\n\u003cli\u003e85 SX 2003-2012\u003c\/li\u003e\n\u003cli\u003e85 SX 17\/14 2013-2024\u003c\/li\u003e\n\u003cli\u003e85 SX 19\/16 2013-2024\u003c\/li\u003e\n\u003c\/ul\u003e\n\n","brand":"KTM","offers":[{"title":"Default Title","offer_id":50968342462711,"sku":"SXS02125071","price":53.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0620\/6364\/0823\/files\/Factory-Spark-Plug-SXS-12502-SXS02125071-Motorcycle-Vehicle-Parts-Plug.webp?v=1784906093","url":"https:\/\/ktmdirect.co.uk\/products\/factory-spark-plug-sxs-12502-sxs02125071","provider":"KTM Direct","version":"1.0","type":"link"}
