Every fraction of a second counts when you are pushing a KTM to its limits, and ignition reliability is non-negotiable. 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.
The 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.
A 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.
