Walker Products 921-2151 Ignition Coil

Walker Products Ignition coils are designed for the professional technician and meet or exceed OEM manufacturers specifications in fit form and function. The primary winding of the ignition coil is wound with a small number of turns and has a small resistance. Applying the battery to this coil causes a sizable DC current to flow. The secondary coil has a much larger number of turns and therefore acts as a step-up transformer. But instead of operating on AC voltages, this coil is designed to produce a large voltage spike when the current in the primary coil is interrupted. Modern coil designs produce voltage pulses up in the neighborhood of 40,000 volts from the interruption of the 12-volt power supplied by the battery. Some modern engines have multiple ignition coils mounted directly on the sparkplugs. Instead of single voltage pulses, they may under some engine conditions produce three voltage pulses. The ignition coil is a compact, electrical transformer that boosts the battery's 12 volts to as high as 40,000 volts. Walker Products began supplying the fuel system and engine management needs of the automotive industry since 1946. As an ISO 9001:2015/TS16949 certified company, we are committed to supplying the highest quality products.
