Innokin X.i Coils – iClear XI Coils from Innokin. 2.1 ohm resistance. The iClear tank needs to be empty before coil change as you need to remove the glass to get to the coil. The new coil should be left sat in the liquid for 20-30 mins before using your kit. This is to allow the liquid to fully soak into the wicking material.
