Denso Ignition Coils

Denso developed the auto industry's first compact stick-type ignition coil. The space-saving design of Denso ignition coils requires no high-tension ignition cables, fitting neatly into the engine's spark plug bore. Along with its stick coil technology, other advanced features include micro-sized driver circuits and diagonal inductive windings. That same expertise is put to use on all Denso ignition coils regardless of their configuration. Each Denso ignition coil is designed and optimized for its specific application, then continually improved by Denso's global engineering team. One key to effective combustion in today's low-emission, high-efficiency engines is consistent, high-energy ignition output. Denso direct ignition coils deliver it. Additional features and benefits of Denso ignition coils include: * Integrated driving circuit in the top of the coil * Superior-quality components and materials ensure optimal performance * Tested and inspected to ensure high quality * Diagonal windings eliminate sectioned bobbins, reducing size and weight * Improved coil efficiency lessens the need to generate high voltage * Eliminates phantom misfires * Small in size, light in weight, and easy to install * Provides maximum available voltage under all operating conditions

MSD Iron Distributor Gears

MSD puts their years of experience to work in making these top-notch iron distributor gears. Their high grade, ductile iron is micro polished for a smooth and scuff-free finish then Melonite QPC coated to reduce friction and initial wear. Excessive clearance causes timing fluctuation throughout the rpm range, resulting in lost horsepower, so MSD also designed these oversized gears for tighter mesh between the camshaft and distributor drive gears.
