DENSO Iridium Spark Plug IW34

DENSO Iridium Spark Plug IW34 (anti-interference), with a thread diameter of 14 mm (long thread). Features the world’s thinnest center electrode, measuring just 0.4 mm in diameter. The U-shaped notched ground electrode concentrates spark formation, resulting in a stronger spark while requiring less current. Additional benefits include easier starting, better acceleration, and lower fuel consumption. Iridium’s extremely high melting point (2500°C) ensures a long service life. The built-in 5 kΩ monolithic resistor provides spark interference suppression. The DENSO IW 34 spark plug is designed for use at temperatures of 30°C and above. It is suitable for many 2-stroke kart engines (e.g., Rotax MAX) and motorcycles.
