SMOKTech’s beautiful line of replacement coil heads for the TFV12 Cloud Beast King completely changed the way vapers think about pre-built atomizer heads. SMOK’s 0.15 ohm V12-X4 replacement coil heads are at the apex of cloud production and flavor potential, presenting an incredible Quad coil arrangement that features two massive dual-parallel Kanthal barrel-coils in vertical alignment. Every replacement V12 atomizer head is constructed out of Stainless Steel and features a Japanese Organic Cotton wick. Additionally, the X4 atomizer heads are equipped with four large wicking ports to provide fast, non-stop wicking during those high-wattage vapes. SMOK’s powerful X4 coil heads perform at their best with high-powered mods; as these replacement heads are rated for best use between a remarkable 100-170W, the X4 heads do not slack on vapor production.
