The quad core alien coil is one of our highest performing wires, consisting of four parallel 28 gauge cores all wrapped with a 36 gauge alien over-wrap. The additional core provides improved density, clouds, and a higher upper wattage limit. These are seriously high performance coils! Resistance is typically very low for this coil, with a 28gx4/36g, 3mm/6 wrap typically around .1 Ohms in dual coil configuration. Due to the complexity of this coil, it is almost entirely hand-made with minimal machine assistance. All of the options are offered as 6 wrap and you can easily remove or add a wrap if needed.
