EGO Mega Single Coil Cartomizer from Smok Tech.
These are hands down the best cartomizer to come along for awhile! I love these on the KGO!
-Available in 1.7ohm or 3.2ohm single coil
-3.5ml(approximately) juice capacity.
-Fit perfectly on the KGO, other Ego style batteries, or mods with Ego connections.
