K&S TECHNOLOGIES offers interference suppressors designed to ensure optimum transmission of high-voltage current to the spark plug, while limiting electromagnetic interference that can disrupt ignition. They generally incorporate an internal resistor of around 5 kΩ to stabilize the spark and improve engine combustion. Their robust, waterproof design effectively protects against the humidity, dust and vibrations encountered in motocross, ensuring high reliability, durability and consistent performance even in intensive off-road use.
