That is the lowest resistance of any helically wound wire. The low resistance results in less loss in spark energy so more reaches the spark plug. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire.
Wires are a little too long by maybe 2-3 inches. Have a lot of excess wire that can't be strapped down. Other than that great quality product. I also ordered to MSD Ignition coils for my dodge at the same time I ordered these. The seller combined both products into a single box. Would definitely recommend to anybody looking to purchase these
