When it comes to describing the process of a vehicle’s ignition and the role played by ignition parts, the old cautionary phrase “fire in the hole” seems most applicable. Small, sequential explosions must be ignited in each piston chamber to drive each piston. The pistons, in turn, drive the rotary process which ultimately moves the vehicle. Ignition systems and their ignition parts literally spark that sequence. Zoro supplies ignition parts such as ignition distributor caps, ignition capacitors, ignition coil resistors and more to help turnover your vehicle engines. Manufacturers include Adelco, Bosch and others. For more on other types of car parts, see our aftermarket rotating electrical, professional brakes, and emission control items.
