Иридиевые импульсные свечи Pulstar Iridium для двигателей Mazda 2,3 Turbo (Mazda MPS и CX-7).
Это свечи, но не зажигания, а импульсные.
Механизм их работы можно понять из изображения свечи в разрезе (в сравнении со свечой зажигания) и описания производителя:

Pulstar Pulse Plugs are unlike any other spark plug made. They store and deliver a powerful pulse of up to 1 Million watts of peak power, whereas normal spark plugs typically deliver 50 watts of peak power. This is done by their internal pulse circuit which generates a much larger spark, at twice the speed of a traditional spark plug. This larger ignition allows for more complete burning of the air/fuel mixture in the cylinder, in turn creating more torque in the crankshaft, more liveliness in the throttle and more power to the wheels. At this point you can enjoy the extra power, or ease off on the accelerator and benefit from the increasing fuel economy. Pulstar Iridium Plugs offer increased performance and horse power. Benefits include up to 12% additional horse power and torque, more precise and efficient combustion, better throttle response, and a 100,000 mile warranty.

Pulstar Pulse Plugs incorporate a pulse circuit, which stores incoming electrical energy from the ignition system and releases it in a powerful pulse of power. Spark plugs waste energy by heating ignition components before the spark occurs. Pulse plugs capture wasted energy with a pulse circuit and then release the captured energy into and beyond the spark gap. When the ignition signals a traditional spark plug, it begins to ionize the spark gap. This means that the voltage builds in the gap until a spark can be formed. During this ionization phase, which lasts about 5 millionths of a second, the incoming voltage (which has nowhere to go) heats up ignition components including the spark plug. This is wasted energy. When the ignition voltage overcomes the resistance in the spark gap, the spark is created with an initial discharge of approximately 50 watts. Once created, the spark resides between the electrodes at very low power for over a period of 30 millionths of a second. Instead of heating ignition parts during the ionization phase, Pulse plugs store this energy in the integral circuit inside the plug. When the ignition power overcomes the resistance in the spark gap, the pulse circuit discharges all of its accumulated power - 1 million watts - in 2 billionths of a second!
