K&S Technologies offers spark plug caps designed with an integrated resistor of around 5 kΩ to limit electromagnetic interference and ensure a more stable, even spark, improving ignition quality and engine combustion. They are made from robust, waterproof materials such as rubber and reinforced plastic, offering excellent resistance to humidity, dust, vibration and the high temperatures encountered in motocross. Their design guarantees high durability, simple installation and consistent reliability, while reducing the risk of misfiring and optimizing overall engine performance under heavy use.
