Seamless engine maintenance: Compatible with a variety of car models and supports 14mm and 16mm spark plugs for comprehensive coverage, ensuring optimal functionality during maintenance. Durable construction: Made from high quality alloy steel with precise heat treatment for outstanding hardness and long durability, enabling efficient and effective use over time. Efficient spark plug extraction: Increased grip friction and a raised design enhance leverage, making spark plug removal easier and faster. Magnetic innovation: Built-in strong magnet holds spark plugs during installation or removal, preventing loss and saving time by avoiding drops. 2-3 practical use scenarios: - In a home garage, service vehicles with 14mm or 16mm spark plugs for routine maintenance or replacements. - In a workshop or service bay handling multiple vehicles with different plug sizes, reducing tool-switching and increasing efficiency. - On the roadside for quick spark plug changes, where the magnetic feature helps prevent dropping the plug during installation or removal.
