The easiest way to improve engine ignition power is to change the resistance of the ignition wire. An hence more current will flow through the spark plug for bigger ignition power. Problem is, the large amount of current plow through the wire core will induce a large amount of magnetic interference at the same time.Hence affect car computer and electrical components. But new Arospeed Triple Core with its 3 individual core built in, allow large current to flow through 3 smaller core and hence greatly reduce magnetic interference by 300%. At the same time allow bigger energy to improve ignition power.
