Distributor VS Wasted Spark VS Coil on Plug VS MONSTER Coil near Plug

Important: Some AEM products may be used solely on the race track and never on public roads or highways. It is the responsibility of the user of any Race-Only products to ensure that they are used in compliance with all applicable laws and regulations. Please check your local laws and regulations before purchasing or installing AEM Performance Electronics Race-Only products for your vehicle. In today&video we are comparing four different kinds of ignition systems for car engines. A distributor based single coil ignition system, a wasted spark ignition system, a coil on plug or direct ignition system and an aftermarket racing coil near plug system. We&starting with the oldest and therefore most primitive setup of the bunch, the distributor. Unlike any of the other ignition systems shown today the distributor controls ignition timing by relying on a mechanical connection to the engine. The distributor is connected to and rotated by engine internals (most often the camshaft) and the speed of the movement of the rotor inside it is synced to the speed of the rotation of the engine. Although it&a system that performs it&duty fine it&obsolete by today&standards and has bay disadvantages over all other ignition systems. The distributor is a source of friction because it adds moving parts to the engine. It&a source of potential oil leaks because the lower part of it&shaft is immersed in engine oil and thus needs to seal it away. On top of this it employs long spark plug wires...
