Not only did insulation join the features list for plug wires, increasing use of electronics as the decades wore on required the development of EMI and RFI suppression. A Heli-Core wire (one that uses a spiral wound core and conductive layer) like most aftermarket performance wires will be one of the best upgrades over a factory set of wires. The higher voltage of a coil on plug or distributor system can create enough voltage that a slightly higher resistance wire will not greatly affect spark strength, but the relatively lower output of a magneto means using a lower resistance wire is more important to ensure a hot spark from the spark plug. Yet again, not quite. They mainly come in black, but you can also get them in yellow, orange, red and blue. I knew about the calculation tip..just was wondering what people were using first hand for heater hoses that looked the best.
That hotter spark can create a more even burn of the fuel/air mixture in the cylinder, and thus, more power output from the engine.
