{"product_id":"denso-iridium-zundkerze-iw29","title":"DENSO Iridium Spark Plug IW29","description":"DENSO Iridium Spark Plug IW29 (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. The extremely high melting point of iridium (2500°C) ensures a long service life. The built-in 5 kOhm monolithic resistor provides spark suppression.  The DENSO IW 29 spark plug is designed for use at temperatures ranging from 20°C to 30°C. It is suitable for many 2-stroke kart engines (e.g., Rotax MAX) and motorcycles.
