A leader in direct ignition technology, DENSO developed the auto industry's first compact stick-type ignition coil. The space-saving design, since adopted by many of the world's leading automakers, requires no high-tension ignition cable, fitting neatly into the engine's spark plug bore. Along with its stick coil technology, other advanced features pioneered by DENSO include micro-sized driver circuits and diagonal inductive windings. In the development of today's high-tech ignition systems, the automakers and DENSO are full partners
